14.1.2 Registers
14.2 Dependencies
14.2.1 I/O Pins
Parallel Port G uses the pins PG0 through PG7. These pins can be used individually as
data inputs or outputs, or as clocked SDLC/HDLC Serial Ports E and F.
All pins are set as inputs on startup, and the alternate pin functions are disabled.
14.2.2 Clocks
All outputs on Parallel Port G are clocked by the peripheral clock divided by two unless
changed in PGCR, where the option of updating the Parallel Port G pins can be synchro-
nized to the output of Timer A1, Timer B1, or Timer B2.
