Port 6 is a 4-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
Port 2 is a 7-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 2 outputs can be configured as
push/pull or open drain drivers.
The following Port 2 pins also serve for alternate functions:
EX1IN
Fast External Interrupt 1 Input
EX2IN
Fast External Interrupt 2 Input
EX3IN
Fast External Interrupt 3 Input
EX4IN
Fast External Interrupt 4 Input
EX5IN
Fast External Interrupt 5 Input
EX6IN
Fast External Interrupt 6 Input
EX7IN
Fast External Interrupt 7 Input
Port 5 is a 2-bit input-only port with Schmitt-Trigger char.
The pins of Port 5 also serve as timer inputs:
T4EUD
GPT1 Timer T4 Ext. Up/Down Ctrl. Input
T2EUD
GPT1 Timer T5 Ext. Up/Down Ctrl. Input
Digital Supply Voltage:
+ 5 V during normal operation and idle mode.
+ 3.3 V during reduced supply operation and idle mode.
2.5 V during power down mode.
Note: Please refer to the Operating Conditions Parameters.
Digital Ground.
