NOTE

PS[7:4] are not available in 80-pin packages.

23.0.7.8

Port M

This port is associated with the CAN40 and SPI0. Port M pins PM[7:0] can be used for either

general purpose I/O, or with the CAN, SCI and SPI subsystems.

The CAN0, CAN4 and SPI0 pins can be re-routed. Refer to Section 23.0.5.37, “Module Routing

NOTE

PM[7:6] are not available in 80-pin packages.

23.0.7.9

Port P

This port is associated with the PWM, SPI1 and SPI2. Port P pins PP[7:0] can be used for either

general purpose I/O, or with the PWM and SPI subsystems.

The pins are shared between the PWM channels and the SPI1 and SPI2. If the PWM is enabled the

pins become PWM output channels with the exception of pin 7 which can be PWM input or output.

If SPI1 or SPI2 are enabled and PWM is disabled, the respective pin configuration is determined

by status bits in the SPI.

The SPI1 and SPI2 pins can be re-routed. Refer to Section 23.0.5.37, “Module Routing Register

(MODRR)”.

Port P offers 8 I/O pins with edge triggered interrupt capability in wired-OR fashion

(Section 23.0.8, “Pin Interrupts”).

NOTE

PP[6] is not available in 80-pin packages.

23.0.7.10 Port H

This port is associated with the SPI1, SPI2, SCI4. Port H pins PH[7:0] can be used for either

general purpose I/O, or with the SPI and SCI subsystems. Port H pins can be used with the routed

SPI1 and SPI2. Refer to Section 23.0.5.37, “Module Routing Register (MODRR)”.

Port H offers 8 I/O pins with edge triggered interrupt capability (Section 23.0.8, “Pin Interrupts”).

NOTE

Port H is not available in 80-pin packages.

23.0.7.11 Port J

This port is associated with the chip selects CS0, CS1, CS2 and CS3 as well as with CAN4, CAN0,

IIC1, IIC0, and SCI2. Port J pins PJ[7:4] and PJ[2:0] can be used for either general purpose I/O, or

with the CAN, IIC, or SCI subsystems. If IIC takes precedence the associated pins become IIC
