TABLE 4-9: PORTE FUNCTIONS
TABLE 4-10: SUMMARY OF REGISTERS ASSOCIATED WITH PORTE
Name Bit# Buffer Type Function
RE0/RD/AN5 bit0 ST/TTL
(1)
Input/output port pin or read control input in Parallel Slave Port mode or
analog input.
For RD (PSP mode):
1 = IDLE
0 = Read operation. Contents of PORTD register output to PORTD I/O
pins (if chip selected).
RE1/WR
/AN6 bit1 ST/TTL
(1)
Input/output port pin or write control input in Parallel Slave Port mode
or analog input.
For WR (PSP mode):
1 =IDLE
0 = Write operation. Value of PORTD I/O pins latched into PORTD
register (if chip selected).
RE2/CS
/AN7 bit2 ST/TTL
(1)
Input/output port pin or chip select control input in Parallel Slave Port
mode or analog input.
For CS (PSP mode):
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.
