7. I/O Ports
7.3
7.3.1
Port 6 is an 8-bit input/output port that is also used for input and output of bus control signals
(LWR, HWR, RD, AS, BACK, BREQ, WAIT) and for clock (φ) output.
The port 6 pin configuration is shown in figure 7.2.
See table 7.5 for the selection of the pin functions.
Pins in port 6 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
