Device Overview MC9S12HY/HA-Family
(during master mode) or slave input pin (during slave mode) MOSI of the serial peripheral interface (SPI).
It can be configured as PWM channel 5.
1.7.3.49 PV0 / MISO / PWM4 / SCL / IOC1_0 / M2C0M — Port V I/O Pin 0
PV0 is a general-purpose input or output pin. It can be configured as high current PWM output pin which
can be used for motor driver. It interface to the coil of motor 2. It can be configured as timer (TIM1)
channel 0. It can be configured as the master input (during master mode) or slave output pin (during slave
mode) MISO for the serial peripheral interface (SPI). It can be configured as the serial clock pin SCL of
IIC module. It can be configured as PWM channel 4.
1.7.4 Power Supply Pins
MC9S12HY/HA-Family power and ground pins are described below. Because fast signal transitions place
high, short-duration current demands on the power supply, use bypass capacitors with high-frequency
characteristics and place them as close to the MCU as possible.
NOTE
All VSS pins must be connected together in the application.
1.7.4.1 VDDX / VSSX — Power and Ground Pins for I/O Drivers
External power and ground for I/O drivers. Bypass requirements depend on how heavily the MCU pins are
loaded.
1.7.4.2 VDDR — Power Pin for Internal Voltage Regulator
Power supply input to the internal voltage regulator.
1.7.4.3 VSS3 — Core Ground Pin
The voltage supply of nominally 1.8 V is derived from the internal voltage regulator. The return current
path is through the VSS3 pin. No static external loading of these pins is permitted.
1.7.4.4 VSSPLL — Ground Pin for PLL
This pin provides ground for the oscillator and the phased-locked loop. The voltage supply of nominally
1.8 V is derived from the internal voltage regulator. On 64LQFP, it will be bonded together with VSS3.
1.7.4.5 VDDA/VRH / VSSA/VRL — Power Supply Pins for ATD and Voltage
Regulator and ATD Reference Voltage inputs
These are the power supply and ground input pins for Port AD IO, the analog-to-digital converter and the
voltage regulator. And also server as the reference voltage input pins for the analog-to-digital converter.
