61 / 248 page  TMP93CS40/TMP93CS41 2004-02-10 93CS40-59 3.5.2 Port 1 (P10 to P17) Port 1 is an 8-bit general-purpose I/O port. I/O can be set on a bit basis using control register P1CR and function register P1FC. Resetting resets all bits of output latch P1, control register P1CR, and function register P1FC to 0, and sets port 1 to input mode. In addition to functioning as a general-purpose I/O port, port 1 also functions as an address data bus (AD8 to AD15) or an address bus (A8 to A15). In the TMP93CS41, which needs external ROMs, port 1 always functions either as an address data bus (AD8 to AD15) when AM8/ AM16 = “0”, or as an address bus (A8 to A15) when AM8/ AM16 = “1”, regardless of the value set in control register P1CR.
