10.15
Port G is a 7-bit I/O port that also has other functions. The port G has the following registers.
• Port G data direction register (PGDDR)
• Port G data register (PGDR)
• Port G register (PORTG)
• Port Function Control Register 0 (PFCR0)
10.15.1 Port G Data Direction Register (PGDDR)
The individual bits of PGDDR specify input or output for the pins of port G.
PGDDR cannot be read; if it is, an undefined value will be read.

Modes 7 (when EXPE = 1), 1, 2, and 4
Pins PG6 to PG4 function as bus control
input/output pins (BREQO, BACK, and BREQ)
when the appropriate bus controller settings are
made. Otherwise, these pins are I/O ports, and their
functions can be switched with PGDDR.
When the CS output enable bits (CS3E to CS0E)
are set to 1, pins PG3 to PG0 function as CS output
pins when the corresponding PGDDR bit is set to 1,
and as input ports when the bit is cleared to 0.
When CS3E to CS0E are cleared to 0, pins PG3 to
PG0 are I/O ports, and their functions can be
switched with PGDDR.
Mode 7 (when EXPE = 0)
Pins PG6 to PG0 are I/O ports, and their functions
can be switched with PGDDR.
