Usage of pins for TPC, 16-bit timer, and 8-bit timer input and output is described in the sections
on those modules. For output of address bits A
Release Control Register (BRCR). Pins not assigned to any of these functions are available for
generic input/output. Figure 7.6 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.
