General Description
1.4.8 ADC Reference High Voltage Pin (V_REFH)
V_REFH provides the reference high voltage for the Analog-to-Digital
Converter (ADC). See Analog-to-Digital Converter (ADC-15) on page
411.
1.4.9 ADC Analog Power Supply Pin (V_DDAREF)
V_DDAREF is the power supply pin for the analog portion of the Analog-to-
Digital Converter (ADC). See Analog-to-Digital Converter (ADC-15)
on page 411.
1.4.10 External Filter Capacitor Pin (CGMXFC)
CGMXFC is an external filter capacitor connection for the Clock
Generator Module (CGM). See Clock Generator Module (CGM) on
page 117.
1.4.11 Port A Input/Output (I/O) Pins (PTA7–PTA0)
PTA7–PTA0 are general-purpose bidirectional I/O port pins. See I/O
Ports on page 293.
1.4.12 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 Analog-to-Digital Converter
(ADC-15) on page 411 and I/O Ports on page 293.
1.4.13 Port C I/O Pins (PTC5–PTC0)
PTC5–PTC3 and PTC1–PTC0 are general-purpose bidirectional I/O
port pins. PTC2/MCLK is a special function port that shares its pin with
the system clock. See I/O Ports on page 293.
