Address and Data Buses
Because the data bus is multiplxed with the address bus, even in the C and D configurations, address bits also
appear on the AD bus prior to the data being accepted or provided.
Upon reset, all of Ports 0–2 are configured as general-purpose input ports; programming is required to use them
as address or data bus pins.
Address and data bus configurations are selectable through the programming of the P1CR, P1FC, P2CR and
P2FC registers.

Supported Configurations
A23/A0–A7) pins can be configured as the address and data buses. The TMP1940CYAF supports the
following four bus configurations.
States of the Address Bus During On-Chip Address Accesses
presented. During this time, the address/data bus assumes the high-impedance state.
For external memory interface, Port 0 (AD0–AD7), Port 1 (AD8–AD15/A8–A15) and Port 2 (A16–
While an on-chip address is being accessed, the address bus maintains the previous address externally
