General Description
1.3.5 Analog Power Supply Pin (V_DDA)
V_DDA is the power supply pin for the analog portion of the CGM. See Chapter 4 Clock Generator Module
(CGM).
1.3.6 Analog Ground Pin (V_SSA)
V_SSA is the ground connection for the analog portion of the CGM. See Chapter 4 Clock Generator Module
(CGM).
1.3.7 ADC Analog Ground Pin (AV_SS/V_REFL)
The AV_SS/V_REFL pin provides both the analog ground connection and the reference low voltage for the
ADC. See Chapter 3 Analog-to-Digital Converter (ADC) Module.
1.3.8 ADC Reference High Voltage Pin (V_REFH)
V_REFH provides the reference high voltage for the ADC. See Chapter 3 Analog-to-Digital Converter (ADC)
Module.
1.3.9 ADC Analog Power Supply Pin (V_DDAREF)
V_DDAREF is the power supply pin for the analog portion of the ADC. See Chapter 3 Analog-to-Digital
Converter (ADC) Module.
1.3.10 External Filter Capacitor Pin (CGMXFC)
CGMXFC is an external filter capacitor connection for the CGM. See Chapter 4 Clock Generator Module
(CGM).
1.3.11 Port A Input/Output (I/O) Pins (PTA7–PTA0)
PTA7–PTA0 are general-purpose bidirectional I/O port pins. See Chapter 13 Input/Output (I/O) Ports.
1.3.12 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 ADC. See Chapter 3
Analog-to-Digital Converter (ADC) Module and Chapter 13 Input/Output (I/O) Ports.
1.3.13 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 Chapter 13 Input/Output (I/O) Ports.
1.3.14 Port D I/O Pins (PTD7–PTD0/ATD8)
Port D is an 8-bit special-function port that shares seven of its pins with the ADC, one of its pins with TIMA,
and one more of its pins with TIMB. See Chapter 17 Timer Interface Module A (TIMA), Chapter 18 Timer
Interface Module B (TIMB), Chapter 3 Analog-to-Digital Converter (ADC) Module, and Chapter 13
Input/Output (I/O) Ports.
