60 / 248 page  TMP93CS40/TMP93CS41 2004-02-10 93CS40-58 3.5.1 Port 0 (P00 to P07) Port 0 is an 8-bit general-purpose I/O port. I/O can be set on a bit basis using the control register P0CR. Resetting resets all bits of P0CR to “0”, and sets port 0 to input mode. In addition to functioning as a general-purpose I/O port, port 0 also functions as an address data bus (AD0 to AD7). To access external memory, port 0 functions as an address data bus (AD0 to AD7), and all bits of the control register P0CR are cleared to “0”. In the TMP93CS41, which needs external ROMs, port 0 always functions as an address data bus (AD0 to AD7) regardless of the value set in control register P0CR.
