Port 7 Input Data Register (P7PIN)
Note: * Depends on the levels of pins P7
When P7PIN is read, the pin states are always read. P7PIN is a read-only register and cannot be
written to. Write access results in writing to PBDDR.

interface 1, with the I
IRQ
Figure 7.16 shows the pin configuration of port 8. The configuration of the pin functions of pins

by bit STAC.
Pins in port 8 can drive one TTL load and a 30-pF capacitive load. They can also drive a
darlington transistor. Pin P8
