topic MC9RS08KA2 A/D conversion in 8-bit Microcontrollers https://community.nxp.com/t5/8-bit-Microcontrollers/MC9RS08KA2-A-D-conversion/m-p/126529#M1115 <HTML><HEAD></HEAD><BODY><DIV>I had a message posted before about using the AN3266 document to do A/D conversion for my MC9RS08KA2 and I have almost debugged all of the code. However, there is one section of the code where the Page Selection Register is initialized with the code of "mov #HREG, PAGESEL" However, there is no variable called HREG in the document. Does anyone know if this vaule is just $00 or is there some other value that is used to set the PAGESEL to an initial value? If anyone has any ideas please let me know. Thank you.</DIV><DIV>&nbsp;</DIV><DIV>Jackabo</DIV></BODY></HTML> Fri, 16 Mar 2007 00:11:31 GMT jackabo 2007-03-16T00:11:31Z MC9RS08KA2 A/D conversion https://community.nxp.com/t5/8-bit-Microcontrollers/MC9RS08KA2-A-D-conversion/m-p/126529#M1115 <HTML><HEAD></HEAD><BODY><DIV>I had a message posted before about using the AN3266 document to do A/D conversion for my MC9RS08KA2 and I have almost debugged all of the code.
