3.3
Pin multiplex
The TX4937 has some multiplexed pins. Each pin is used for different functions depending on the settings
of the ADDR[18]/[9] boot configuration signal. Table 3.3.1 shows how to set the function for each pin.

Note 1: * shows that there is no relationship to the configuration of the corresponding function.
Note 2: One of ECC, PIO[15:8] can be selected (can't use simultaneously).
(Operation is not guaranteed when these functions that cannot be used simultaneously are set up)
Note 3: It shows that these terminals are multiplexed under each function.
Note 4: Blank shows that the terminal isn't multiplexed with the function.
For example, when only ACLC are selected, functions other than DMAREQ[2], DMAACK[2],
PIO[4], PIO[3], PIO[2] can be used.
