Decoupling of these pins should be as per the digital supply. See
(CGM).
1.5.6 External Filter Capacitor Pin (V
CGMXFC is an external filter capacitor connection for the CGM. See
(CGM).

1.5.8 Port A Input/Output (I/O) Pins (PTA7/KBD7–PTA0/KBD0)
PTA7–PTA0 are general-purpose, bidirectional I/O port pins. Any or all of the port A pins can be
programmed to serve as keyboard interrupt pins. PTA7–PTA4 are only available on the 48-pin LQFP
package. See
These port pins also have selectable pullups when configured for input mode. The pullups are disengaged
when configured for output mode. The pullups are selectable on an individual port bit basis.
1.5.9 Port B I/O Pins (PTB7/AD7–PTB0/AD0)
PTB7–PTB0 are general-purpose, bidirectional I/O port pins that can also be used for analog-to-digital
converter (ADC) inputs. PTB7–PTB4 are only available on the 48-pin LQFP package. See
Input/Output (I/O) Ports
1.5.10 Port C I/O Pins (PTC6–PTC0/CAN
PTC6 and PTC5 are general-purpose, bidirectional I/O port pins. PTC4–PTC0 are general-purpose,
bidirectional I/O port pins that contain higher current sink/source capability. PTC6–PTC2 are only
available on the 48-pin LQFP package. See
MSCAN08 Controller
PTC1 and PTC0 can be programmed to be MSCAN08 pins.
These port pins also have selectable pullups when configured for input mode. The pullups are disengaged
when configured for output mode. The pullups are selectable on an individual port bit basis.
1.5.11 Port D I/O Pins (PTD7/T2CH1–PTD0/SS)
PTD7–PTD0 are special-function, bidirectional I/O port pins. PTD3–PTD0 can be programmed to be
serial peripheral interface (SPI) pins, while PTD7–PTD4 can be individually programmed to be timer
interface module (TIM1 and TIM2) pins. PTD7 is only available on the 48-pin LQFP package. See
