ST16C552/552A
Logic 0 = -SLCTIN output is set to a logic 1. (normal
default condition)
Logic 1 = -SLCTIN output is set to a logic 0.
CON BIT-4:
This bit enables or masks the printer interrupt output
-INTP. The state of this bit can be read using COM bit-
4.
Logic 0 = Disable -INTP output. (normal default con-
dition)
Logic 1 = Enable -INTP output.
CON BIT-5:
This bit is used in conjunction with the state of BIDEN
to set the direction (input/output) of the PD7-PD0 data
bus.
Logic 0 + BIDEN 1 = PD7-PD0 are set for output mode
(normal default condition)
Logic 1 + BIDEN 1 = PD7-PD0 are set for input mode
CON BIT 6-7:
Not Used - initialized to a logic 1.
