9.7 Port A

9.7.1 Overview

Port A is an 8-bit input/output port that is also used for address output (A23 to A20), 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 output (TEND1, TEND0) from the DMA controller

(DMAC). Figure 9-8 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.
