For this we need to interface the AFE chip DDC114 from TI to the micro controller via Synchronous Serial Interface. The datasheet of LPC2364 indicate that the SSP module in is capable to operate in 4 wire SSI mode. I would linke to know the pin mapping to be done to operate the SSP module in SSI mode. As per the datasheet of DDC 114 (also as per standard SSI definition) the data and clock are differential, so I would like to know the which&nbsp; SSP clock is to be configured as DOUT+ and DOUT- also which SSP clock should be configured as DCLK+ and DCLK-. if anyone is already done this? please reply..</SPAN><BR /><SPAN>In our application out of two SSP modules we would like to connect one SPI slave and one SSI connection to DDC114, I have completed an initial level pin mapping with given pin description in the datasheet,</SPAN><BR /><BR /><SPAN>For SPI connection</SPAN><BR /><BR /><SPAN>[color=#f00]SPI CLOCK&nbsp;&nbsp; - SCK — Serial clock for SPI.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 62&nbsp;&nbsp;&nbsp;&nbsp; - P0[15]/TXD1/SCK0/SCK</SPAN><BR /><SPAN>SPI C/S&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - SSEL — Slave Select for SPI.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 63&nbsp;&nbsp;&nbsp;&nbsp; - P0[16]/RXD1/SSEL0/SSEL</SPAN><BR /><SPAN>SPI MISO&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - MISO — Master In Slave Out for SPI.&nbsp;&nbsp;&nbsp; - Pin no 61&nbsp;&nbsp;&nbsp;&nbsp; - P0[17]/CTS1/MISO0/MISO</SPAN><BR /><SPAN>SPI MOSI&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - MOSI — Master Out Slave In for SPI.&nbsp;&nbsp;&nbsp; - Pin no 60&nbsp;&nbsp;&nbsp;&nbsp; - P0[18]/DCD1/MOSI0/MOSI[/color]</SPAN><BR /><BR /><SPAN>For SSI connection</SPAN><BR /><BR /><SPAN>[color=#0c0]SSI CLOCK</SPAN><BR /><SPAN>SSI_CLK+&nbsp;&nbsp;&nbsp;&nbsp; - SCK0 — Serial clock for SSP0.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 34&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - P1[20]/PWM1[2]/SCK0</SPAN><BR /><SPAN>SSI_CLK-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - SCK1 — Serial Clock for SSP1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 78&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - P0[7]/I2STX_CLK/SCK1/MAT2</SPAN><BR /><BR /><SPAN>SSI DATAOUT</SPAN><BR /><SPAN>SSI_DOUT+&nbsp; - MOSI0 — MOSI for SSP0.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 38&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - P1[24]/PWM1[5]/MOSI0</SPAN><BR /><SPAN>SSI_DOUT-&nbsp;&nbsp; - MOSI1 — MOSI for SSP1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 76&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - P0[9]/I2STX_SDA/MOSI1/MAT2[3]</SPAN><BR /><BR /><SPAN>SSI DATA IN</SPAN><BR /><SPAN>SSI_DIN+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - MISO0 — MISO for&nbsp; SSP0.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 37&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - P1[23]/PWM1[4]/MISO0</SPAN><BR /><SPAN>SSi_DIN-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - MISO1 — MISO for SSP1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Pin no 77&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - P0[8]/I2STX_WS/MISO1/MAT2[2][/color]</SPAN><BR /><BR /><SPAN>Can anyone check and let me know if there is any mistake?</SPAN></BODY></HTML> Wed, 15 Jun 2016 19:50:32 GMT lpcware 2016-06-15T19:50:32Z LPC2364 SSI pin mapping https://community.nxp.com/t5/LPC-Microcontrollers/LPC2364-SSI-pin-mapping/m-p/550669#M14056 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by nithin.m@nestgroup.net on Wed Jul 29 00:04:38 MST 2015</STRONG><BR /><SPAN>Hi,</SPAN><BR /><SPAN>We are using the LPC2364 for our new automotive sensor project.
