Timing Chart
Note 1: In case of (3) and (4), the data bus signals output the addresses since the signals are
also used as the address bus. Writing “0” to bit CKOCR<ALEEN>, ALE signal can be
stopped outputting.
Note 2: After reset operation, port 0, port 1 and port 2 of TMP93CS44F function as input
ports.
Note 3: In case of TMP93CS44F, all (1) to (4) can be available using P1CR, P1FC, P2CR
and P2FC registers.
Note 4: In case of TMP93CS45F, case (3) and (4) cannot be available.
