Data Sheet
Function
Port 6 is an 8-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state. Port 6 outputs can be configured as push/
pull or open drain drivers.
The Port 6 pins also serve for alternate functions:
CS0
Chip Select 0 Output
CS1
Chip Select 1 Output
CS2
Chip Select 2 Output
CS3
Chip Select 3 Output
CS4
Chip Select 4 Output
HOLD
External Master Hold Request Input
HLDA
Hold Acknowledge Output (master mode)
or Input (slave mode)
BREQ
Bus Request Output
Port 8 is an 8-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits. For a pin
configured as input, the output driver is put into high-
impedance state. Port 8 outputs can be configured as push/
pull or open drain drivers. The input threshold of Port 8 is
selectable (TTL or special).
The following Port 8 pins also serve for alternate functions:
CC16IO
CAPCOM2: CC16 Capture Inp./Compare Outp.
CC17IO
CAPCOM2: CC17 Capture Inp./Compare Outp.
CC18IO
CAPCOM2: CC18 Capture Inp./Compare Outp.
CC19IO
CAPCOM2: CC19 Capture Inp./Compare Outp.
CC20IO
CAPCOM2: CC20 Capture Inp./Compare Outp.
CC21IO
CAPCOM2: CC21 Capture Inp./Compare Outp.
CC22IO
CAPCOM2: CC22 Capture Inp./Compare Outp.
CC23IO
CAPCOM2: CC23 Capture Inp./Compare Outp.
