For register reads, I believe that is really doesn't matter that the chip is always selected using /CHIPSEL as it will only present or latch data on an IOR or IOW strobe. However, I have not used the chip in its 16-bit mode; it looks like the registers are memory mapped to 0x0000'0300. Can you post a small piece of code that reads and writes the registers? -- Paul Curtis, Rowley Associates Ltd http://www.rowley.co.uk CrossWorks for MSP430, ARM, AVR and (soon) MAXQ processors
