open-drain output pins. The CAN4 pins can be re-routed. Refer to
Register
Port J pins can be used with the routed CAN0 modules. Refer to
Register
Port J offers 7 I/O pins with edge triggered interrupt capability
23.0.7.12 Port AD0
This port is associated with the ATD0. Port AD0 pins PAD07–PAD00 can be used for either general
purpose I/O, or with the ATD0 subsystem.
23.0.7.13 Port AD1
This port is associated with the ATD1. Port AD1 pins PAD23–PAD8 can be used for either general
purpose I/O, or with the ATD1 subsystem.
23.0.8
Ports P, H and J offer pin interrupt capability. The interrupt enable as well as the sensitivity to rising or
falling edges can be individually configured on per-pin basis. All bits/pins in a port share the same
interrupt vector. Interrupts can be used with the pins configured as inputs or outputs.
An interrupt is generated when a bit in the port interrupt flag register and its corresponding port interrupt
enable bit are both set. The pin interrupt feature is also capable to wake up the CPU when it is in STOP or
WAIT mode.
A digital filter on each pin prevents pulses
interrupt. The minimum time varies over process conditions, temperature and voltage
