85 / 790 page  Port Integration Module (S12HYPIMV1) MC9S12HY/HA-Family Reference Manual, Rev. 1.04 Freescale Semiconductor 85 Table 2-19. PTS Register Field Descriptions Field Description 7 PTS Port S general purpose input/output data—Data Register, SPI SS inout, IIC SDA inout, PWM channel3 When not used with the alternative function, the associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is driven to the pin. If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered pin input state is read. • The SPI takes precedence over the IIC, PWM3 and the general purpose I/O function if enabled • The IIC takes precedence over the PWM3 and the general purpose I/O function if enabled • The PWM3 takes precedence over the general purpose I/O function if enabled 6 PTS Port S general purpose input/output data—Data Register, SPI SCK inout, PWM channel2 When not used with the alternative function, the associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is driven to the pin. If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered pin input state is read. • The SPI takes precedence over the PWM2 and the general purpose I/O function if enabled • The PWM2 takes precedence over the general purpose I/O function if enabled 5 PTS Port S general purpose input/output data—Data Register, SPI MOSI inout, PWM channel1 When not used with the alternative function, the associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is driven to the pin. If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered pin input state is read. • The SPI takes precedence over the PWM1 and the general purpose I/O function if enabled • The PWM1 takes precedence over the general purpose I/O function if enabled 4 PTS Port S general purpose input/output data—Data Register, SPI MISO inout, IIC SCL inout, PWM channel0 When not used with the alternative function, the associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is driven to the pin. If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered pin input state is read. • The SPI takes precedence over the IIC, PWM0 and the general purpose I/O function if enabled • The IIC takes precedence over the PWM0 and the general purpose I/O function if enabled • The PWM0 takes precedence over the general purpose I/O function if enabled 3 PTS Port S general purpose input/output data—Data Register, CAN TX When not used with the alternative function, the associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is driven to the pin. If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered pin input state is read. • The CAN takes precedence over the general purpose I/O function if enabled 2 PTS Port S general purpose input/output data—Data Register, CAN RX When not used with the alternative function, the associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is driven to the pin. If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered pin input state is read. • The CAN takes precedence over the general purpose I/O function if enabled |
