DESCRIPTION

IOxDAT

15-0

R/W

Depends on the signal level on

Data bits that are used to either control the level of the

the corresponding I/O pin

corresponding I/O pins configured as output pins or to

monitor the level of the corresponding I/O pins configured

as input pins. The function of the data register bits is

determined by the setting of the direction register bits. See

Table 3-36, TMS320VC5502 PGPIO Cross-Reference to

determine which device pins correspond to the PGPIO

pins.

If IOxEN = 0 and IOxDIR = 0, then IOxDAT is used to

read the value of the PGPIOx pin:

•

IOxDAT = 0: PGPIOx pin is read as a low

•

IOxDAT = 1: PGPIOx pin is read as a high

If IOxEN = 1 and IOxDIR = 1, then IOxDAT is used to set

the value of the PGPIOx pin:

•

IOxDAT = 0: Set PGPIOx pin to low

•

IOxDAT = 1: Set PGPIOx pin to high

Note that other combinations of IOxEN and IOxDIR are

not supported—i.e., IOxEN and IOxDIR must always be

set to the same value.
