General Description
Pin Assignments
External interrupt
pin (IRQ)
IRQ is an asynchronous external interrupt pin. See
External Interrupt Module (IRQ) on page 171.
Analog power
supply pin (V_DDA)
V_DDA is the power supply pin for the clock generator module (CGM).
Analog ground pin
(V_SSA)
The V_SSA analog ground pin is used only for the ground connections for
the clock generator module (CGM) section of the circuit and should be
decoupled as per the V_SS digital ground pin. See
Clock Generator Module (CGM) on page 107.
Analog ground pin
(A_VSS/VREFL)
The A_VSS analog ground pin is used only for the ground connections for
the analog to digital convertor (ADC) and should be decoupled as per
the VSS digital ground pin.
ADC voltage
reference pin
(VREFH)
VREFH is the power supply for setting the reference voltage VREFH.
Connect the VREFH pin to a voltage potential<= V_DDAREF, not less than
1.5V.
Analog supply pin
(V_DDAREF)
The V_DDAREF analog supply pin is used only for the supply connections
for the analog to digital convertor (ADC).External filter capacitor pin
(CGMXFC)
CGMXFC is an external filter capacitor connection for the CGM. See
Clock Generator Module (CGM) on page 107.
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 327.
