C1 through C5 are set to 1 or 0. The data appears latched on the C1 through C5 SLIC I/O pins,
provided they are set in the Output mode (see Command 17). The data sent to any of the pins
set to the Input mode are latched, but do not appear at the pins.
RSVD
The logic state of pins C1 through C5 is read regardless of the direction programmed into the
Input/Output register.
Pins C1x through C5x are set to input or output modes individually. Pins C51 and C52 are not
available on the Am79C03(A). C51 and C52 pins are output only on the Am79C031(A) and must
be programmed as outputs with this command. All unused SLIC I/O pins should be programmed
as outputs to reduce power consumption.
