8.7.1
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 ( ) output.
The pin configuration of port 6 is shown in figure 8.6.
In modes 1 to 5 (expanded modes), the pin functions are P6
AS, P6
In mode 7 (single-chip mode), P6
function as generic input/output ports.
When DRAM is connected to areas 2 to 5, LWR, HWR, and RD also function as LCAS, UCAS,
and WE, respectively. For details see section 6.5, DRAM Interface.
Pins in port 6 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
