5.7 Port 6
Port 6 is a 7-bit input/output port that also provides input and output pins for the free-running timer,
and interrupt request input pins (IRQ0 to IRQ2). The pin functions depend on control bits in the
free-running timer control registers and IRQ enable register. Pins not used for timer or interrupt
functions are available for general-purpose input/output. Table 5-12 lists the pin functions, which
are the same in both the expanded and single-chip modes.
