General Description
MOTOROLA
General Description
any internal reset source is asserted. See
1.5.4 External Interrupt Pin (IRQ)
IRQ is an asynchronous external interrupt pin. See
1.5.5 CGM Power Supply Pins (V
DDA
and V
SSA
)
V
DDA
and V
SSA
are the power supply pins for the analog portion of the
clock generator module (CGM). Decoupling of these pins should be per
the digital supply. See
the digital supply. See
1.5.6 External Filter Capacitor Pin (CGMXFC)
CGMXFC is an external filter capacitor connection for the CGM. See
1.5.7 Analog Power Supply Pins (V
DDA
and V
SSA
)
V
DDAD
and V
SSA
are the power supply pins for the analog-to-digital
converter. Decoupling of these pins should be per the digital supply. See
1.5.8 ADC Voltage Decoupling Capacitor Pin (V
REFH
)
V
REFH
is the power supply for setting the reference voltage. Connect the
V
REFH
pin to the same voltage potential as V
DDAD
.
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
SSAD
. See
