REGISTER 13-7: ODCONA: PORTA OPEN DRAIN CONTROL REGISTER
R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0
ODA7 ODA6 ODA5 ODA4 ODA3 ODA2 ODA1 ODA0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-0 ODA<7:0>: PORTA Open Drain Enable bits
For RA<7:0> pins, respectively
1 = Port pin operates as open-drain drive (sink current only)
0 = Port pin operates as standard push-pull drive (source and sink current)
REGISTER 13-8: SLRCONA: PORTA SLEW RATE CONTROL REGISTER
R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1 R/W-1/1
SLRA7 SLRA6 SLRA5 SLRA4 SLRA3 SLRA2 SLRA1 SLRA0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-0 SLRA<7:0>: PORTA Slew Rate Enable bits
For RA<7:0> pins, respectively
1 = Port pin slew rate is limited
0 = Port pin slews at maximum rate
REGISTER 13-9: INLVLA: PORTA INPUT LEVEL CONTROL REGISTER
R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0 R/W-0/0
INLVLA7 INLVLA6 INLVLA5 INLVLA4 INLVLA3 INLVLA2 INLVLA1 INLVLA0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-0 INLVLA<7:0>: PORTA Input Level Select bits
For RA<7:0> pins, respectively
1 = ST input used for PORT reads and interrupt-on-change
0 = TTL input used for PORT reads and interrupt-on-change
