REGISTER 11-8: SLRCONA: PORTA SLEW RATE CONTROL REGISTER
U-0 U-0 R/W-1/1 R/W-1/1 U-0 R/W-1/1 R/W-1/1 R/W-1/1
— — SLRA<5:4> — SLRA<2:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit
u = Bit is unchanged x = Bit is unknown U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set ‘0’ = Bit is cleared -n/n = Value at POR and BOR/Value at all other Resets
bit 7-6 Unimplemented: Read as ‘0’
bit 5-4 SLRA<5:4>: PORTA Slew Rate Enable bits
For RA<5:4> Pins, Respectively:
1 = Port pin slew rate is limited
0 = Port pin slews at maximum rate
bit 3 Unimplemented: Read as ‘0’
bit 2-0 SLRA<2:0>: PORTA Slew Rate Enable bits
For RA<2:0> Pins, Respectively:
1 = Port pin slew rate is limited
0 = Port pin slews at maximum rate
REGISTER 11-9: INLVLA: PORTA INPUT LEVEL CONTROL REGISTER
U-0 U-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
— — INLVLA5 INLVLA4 INLVLA3 INLVLA2 INLVLA1 INLVLA0
bit 7 bit 0
Legend:

u = Bit is unchanged x = Bit is unknown U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set ‘0’ = Bit is cleared -n/n = Value at POR and BOR/Value at all other Resets
bit 7-6 Unimplemented: Read as ‘0’
bit 5-0 INLVLA<5:0>: PORTA Input Level Select bits
For RA<5:0> Pins, Respectively:
1 = ST input is used for PORT reads and Interrupt-On-Change
0 = TTL input is used for PORT reads and Interrupt-On-Change
