In single chip mode, the MC68HC05E6 has a total of 32 I/O lines,
arranged as three 8-bit I/O ports (A, B and D), one 8-bit I/O port (C)
which shares two pins with the timer subsystem, and one 4-bit input-only
port (G) which is shared with the A/D converter. Each I/O line is
individually programmable as either input or output, under the software
control of the data direction registers. All of the port C pins can be
configured to respond to keyboard interrupts.
To avoid glitches on the output pins, data should be written to the I/O port
data register before writing ones to the corresponding data direction
register bits to set the pins to output mode.
