General Description
1.5.9 ADC Voltage Reference Low Pin (V_REFL)
V_REFL is the lower reference supply for the ADC. Connect the V_REFL pin
to the same voltage potential as V_SSA. (See Section 19. Analog-to-
Digital Converter (ADC).)
1.5.10 Port A Input/Output (I/O) Pins (PTA7–PTA0)
PTA7–PTA0 are general-purpose bidirectional I/O port pins. (See
Section 15. Input/Output (I/O) Ports.)
1.5.11 Port B I/O Pins (PTB7/ATD7–PTB0/ATD0)
Port B is an 8-bit special function port that shares all eight pins with the
analog-to-digital convertor (ADC). (See Section 19. Analog-to-Digital
Converter (ADC) and Section 15. Input/Output (I/O) Ports.)
1.5.12 Port C I/O Pins (PTC6–PTC2 and PTC1/ATD9–PTC0/ATD8)
PTC6–PTC2 are general-purpose bidirectional I/O port pins. (See
Section 15. Input/Output (I/O) Ports.) PTC1/ATD9–PTC0/ATD8 are
special function port pins that are shared with the analog-to-digital
convertor (ADC). (See Section 19. Analog-to-Digital Converter (ADC)
and Section 15. Input/Output (I/O) Ports.)
1.5.13 Port D Input-Only Pins (PTD6/IS3–PTD4/IS1 and PTD3/FAULT4–PTD0/FAULT1)
PTD6/IS3–PTD4/IS1 are special function input-only port pins that also
serve as current sensing pins for the pulse width modulator module
(PWMMC). PTD3/FAULT4–PTD0/FAULT1 are special function port pins
that also serve as fault pins for the pulse width modulator module
(PWMMC). (See Section 9. Pulse Width Modulator for Motor Control
(PWMMC) and Section 15. Input/Output (I/O) Ports.)
