TABLE 9-8: SUMMARY OF REGISTERS ASSOCIATED WITH PORTD
Name Bit# Buffer Type Function
RD0/PSP0 bit0 ST/TTL
(1)
Input/output port pin or parallel slave port bit0.
RD1/PSP1 bit1 ST/TTL
(1)
Input/output port pin or parallel slave port bit1.
RD2/PSP2 bit2 ST/TTL
(1)
Input/output port pin or parallel slave port bit2.
RD3/PSP3 bit3 ST/TTL
(1)
Input/output port pin or parallel slave port bit3.
RD4/PSP4 bit4 ST/TTL
(1)
Input/output port pin or parallel slave port bit4.
