General Description
Pin Assignments
External Reset Pin
(RST)
A logic 0 on the RST pin forces the MCU to a known startup state. RST
is bidirectional, allowing a reset of the entire system. It is driven low when
any internal reset source is asserted. See
System Integration Module (SIM) on page 83 for more information.
External Interrupt
Pin (IRQ)
IRQ is an asynchronous external interrupt pin. See
External Interrupt Module (IRQ) on page 165.
Analog Power
Supply Pin (V_DDA)
V_DDA is the power supply pin for the analog portion of the chip. This pin
will supply the clock generator module (CGM). See
Clock Generator Module (CGM) on page 105.
Analog Ground
Pin (V_SSA)
The V_SSA analog ground pin is used only for the ground connections for
the analog sections of the circuit and should be decoupled as per the
V_SS digital ground pin. The analog sections consist of a clock generator
module (CGM). See Clock Generator Module (CGM) on page 105.
External Filter
Capacitor Pin
(CGMXFC)
CGMXFC is an external filter capacitor connection for the CGM. See
Clock Generator Module (CGM) on page 105
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 279.
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 converter (ADC). See
Analog-to-Digital Converter (ADC-15) on page 395 and I/O Ports on
page 279.
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
7-gen
