I'm using the LPC11C24 and it has been successful on SSP0. Now I want to use SSP1 is well. I've set the PinMux to:

 

Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO2_2, (IOCON_FUNC1 | IOCON_MODE_INACT));// MISO1
Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO2_3, (IOCON_FUNC1 | IOCON_MODE_INACT));// MOSI1
Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO2_0, (IOCON_FUNC1 | IOCON_MODE_INACT));// SSEL1
Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO2_1, (IOCON_FUNC1 | IOCON_MODE_INACT));// SCK1

#define LPC_SSP           LPC_SSP1

 

Using the same code for the SSP0 and with a scope on SSEL1 and SCK1 I can't see any signals.

 

Is there anything else that need to be configured for use with SSP1?
