MSCAN transmit pin
MSCAN receive pin
8 (KWG4
only)
Key wake-up and general purpose I/O; can cause an interrupt when an input
transitions from high to low. On 80-pin QFP all 8 I/O should be initialised.
KWG[6:0]
PGUPD
9–11, 19–22
13
(1)
Defines if I/O port resistive load is a pull-up or a pull-down, when enabled.

only)
32–35,
49–52
Key wake-up and general purpose I/O; can cause an interrupt when an input
transitions from high to low. On 80-pin QFP all 8 I/O should be initialised.
KWH[7:0]
PHUPD
(2)
41
Defines if I/O port resistive load is a pull-up or a pull-down, when enabled.
1. In the 80-pin version PGUPD is connected internally to VDD
2. In the 80-pin version PHUPD is connected internally to VSS
