ST16C452/452PS
Rev. 3.20
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
[452PS only]
CON BIT 6-7:
Not Used - initialized to a logic 1.
