Section 7 I/O Ports
7.10 Port A
7.10.1 Overview
Port A is an 8-bit input/output port that is also used for output (TP7 to TP0) from the programmable
timing pattern controller (TPC), input and output (TIOCB2, TIOCA2, TIOCB1, TIOCA1, TIOCB0,
TIOCA0, TCLKD, TCLKC, TCLKB, TCLKA) by the 16-bit integrated timer unit (ITU), and
address output (A23 to A20). Figure 7.22 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.
