TABLE 5-9: PORTE FUNCTIONS TABLE 5-10: 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: RD 1 = Not a read operation 0 = Read operation. Reads PORTD register (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: WR 1 = Not a write operation 0 = Write operation. Writes 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: 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. Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Value on: POR, BOR Value on all other resets 09h PORTE — — — — — RE2 RE1 RE0 ---- -xxx ---- -uuu 89h TRISE IBF OBF IBOV PSPMODE — PORTE Data Direction Bits 0000 -111 0000 -111 9Fh ADCON1 — — — — — PCFG2 PCFG1 PCFG0 ---- -000 ---- -000 Legend: x = unknown, u = unchanged, - = unimplemented read as '0'.
