output. A reset or hardware standby leaves port B as an input port. Usage of pins for TPC, ITU,
DMAC, and A/D converter input and output is described in the sections on those modules. For
output of CS
these functions are available for generic input/output. Figure 9.11 shows the pin configuration of
port B.
Pins in port B can drive one TTL load and a 30-pF capacitive load. They can also drive an LED or
darlington transistor pair. Pins PB
