Input/output port pin or read control input in parallel slave port mode
or analog input:
RD
1= Not a read operation
0= Read operation. Reads PORTD register (if chip selected)
ST/TTL(1)
ST/TTL(1)
bit1
bit2
Input/output port pin or write control input in parallel slave port mode
or analog input:
WR
1= Not a write operation
0= Write operation. Writes PORTD register (if chip selected)
Input/output port pin or chip select control input in parallel slave port
mode or analog input:
CS
1= Device is not selected
0= Device is selected
Legend: ST = Schmitt Trigger input, TTL = TTL input
Note 1: Input buffers are Schmitt Triggers when in I/O mode and TTL buffers when in Parallel Slave Port Mode.
