MC9S12H256 Device User Guide — V01.20
2.3.45 PV[3:0] / M2C1P, M2C1M, M2C0P, M2C0M — Port V I/O Pins [3:0]
PV3-PV0 are general purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive. These pins interface to the coils of motor 2. PWM output on
M2C0M results in a positive current flow through coil 0 when M2C0P is driven to a logic high state. PWM
output on M2C1M results in a positive current flow through coil 1 when M2C1P is driven to a logic high
state.
2.3.46 PW[7:4] / M5C1P, M5C1M, M5C0P, M5C0M — Port W I/O Pins [7:4]
PW7-PW4 are general purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive. These pins interface to the coils of motor 5. PWM output on
M5C0M results in a positive current flow through coil 0 when M5C0P is driven to a logic high state. PWM
output on M5C1M results in a positive current flow through coil 1 when M5C1P is driven to a logic high
state.
2.3.47 PW[3:0] / M4C1P, M4C1M, M4C0P, M4C0M — Port W I/O Pins [3:0]
PW3-PW0 are general purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive. These pins interface to the coils of motor 4. PWM output on
M4C0M results in a positive current flow through coil 0 when M4C0P is driven to a logic high state. PWM
output on M4C1M results in a positive current flow through coil 1 when M4C1P is driven to a logic high
state.
2.4 Power Supply Pins
MC9S12H256 power and ground pins are described below.
2.4.1 VDDR — External Power Pin
VDDR is the power supply pin for the internal voltage regulator.
2.4.2 VDDX1, VDDX2, VSSX1, VSSX2 — External Power and Ground Pins
VDDX1, VDDX2, VSSX1 and VSSX2 are the power supply and ground pins for input/output
drivers.VDDX1 and VDDX2 as well as VSSX1 and VSSX2 are not internally connected.

NOTE:
All VSS pins must be connected together in the application (21.2 Recommended
PCB layout).
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. Bypass requirements depend on how heavily
the MCU pins are loaded (Table 21-1).
