Section 9 I/O Ports
9.7
9.7.1
Port 6 is a 7-bit input/output port that is also used for input and output of bus control signals
(LWR, HWR, RD, AS, BACK, BREQ, and WAIT). When DRAM is connected to area 3, LWR,
HWR, and RD also function as LW, UW, and CAS, or LCAS, UCAS, and WE, respectively. For
details see section 7, Refresh Controller.
Figure 9.6 shows the pin configuration of port 6. In modes 1 to 6 (expanded modes) the pin
functions are LWR, HWR, RD, AS, P6
method of selecting the pin states. In mode 7 (single-chip mode) port 6 is a generic input/output
port.
Pins in port 6 can drive one TTL load and a 30-pF capacitive load. They can also drive a
darlington transistor pair.
