In the descriptions of the ports and port registers, the lower-
case letter “x” represents the port designation, either B, C,
G, H, or I. For example, “PxDIR register” means any one of
the port direction registers: PBDIR, PCDIR, PGDIR, PH-
DIR, or PIDIR.
All of the port registers are byte-wide read/write registers,
except for the port data input registers, which are read-only
registers. Each register bit controls the function of the cor-
responding port pin. For example, PGDIR.2 (bit 2 of the
PGDIR register) controls the direction of port pin PG2.
