7.2 Introduction
The MC68HC05C8A has three 8-bit input/output (I/O) ports.These 24
port pins are programmable as either inputs or outputs under software
control of the data direction registers. Port D does not have a data
direction register, and its seven pins are input only with the exception of
certain serial communications (SCI)/serial peripheral interface (SPI)
functions.
NOTE:
To avoid a glitch on the output pins, write data to the I/O port data
register before writing a 1 to the corresponding data direction register.
