9.8 Port A
9.8.1 Overview
Port A is an 8-bit input/output port that is also used for output (TP
programmable timing pattern controller (TPC), input and output (TIOCB
TIOCA
pulse unit (ITU), and output (TEND
same set of pin functions in all operating modes. Figure 9-11 shows the pin configuration of
port A.
Pins in port A can drive one TTL load and a 30-pF capacitive load. They can also drive a
darlington transistor pair. Port A has Schmitt-trigger inputs.
9.8.2 Register Descriptions
