Chapter 1 MC9S12XHZ Family Device Overview
1.2.3.46 PT7 / IOC7 / SCL1 — Port T I/O Pin 7
PT7 is a general-purpose input or output pin. It can be configured as input capture or output compare pin
IOC7 of the enhanced capture timer (ECT) or the serial clock pin SCL1 of the inter-IC bus interface 1
(IIC1).
1.2.3.47 PT6 / IOC6 / SDA1 — Port T I/O Pin 6
PT6 is a general-purpose input or output pin. It can be configured as input capture or output compare pin
IOC6 of the enhanced capture timer (ECT) or the serial data pin SDA1 of the inter-IC bus interface 1
(IIC1).
1.2.3.48 PT5 / IOC5 / SCL0 — Port T I/O Pin 5
PT5 is a general-purpose input or output pin. It can be configured as input capture or output compare pin
IOC5 of the enhanced capture timer (ECT) or the serial clock pin SCL0 of the inter-IC bus interface 0
(IIC0).
1.2.3.49 PT4 / IOC4 / SDA0 — Port T I/O Pin 4
PT4 is a general-purpose input or output pin. It can be configured as input capture or output compare pin
IOC4 of the enhanced capture timer (ECT) or the serial data pin SDA0 of the inter-IC bus interface 0
(IIC0).
1.2.3.50 PT[3:0] / IOC[3:0] / FP[27:24] — Port T I/O Pins [3:0]
PT3–PT0 are general-purpose input or output pins. They can be configured as input capture or output
compare pins IOC3–IOC0 of the enhanced capture timer (ECT). They can be configured as frontplane
segment driver outputs FP27–FP24 of the LCD module.
1.2.3.51 PU[7:4] / M1C1(SIN)P, M1C1(SIN)M, M1C0(COS)P, M1C0(COS)M — Port U
I/O Pins [7:4]
PU7–PU4 are general-purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive or to measure the back EMF to calibrate the pointer reset position.
These pins interface to the coils of motor 1.
1.2.3.52 PU[3:0] / M0C1(SIN)P, M0C1(SIN)M, M0C0(COS)P, M0C0(COS)M — Port U
I/O Pins [3:0]
PU3–PU0 are general-purpose input or output pins. They can be configured as high current PWM output
pins which can be used for motor drive or to measure the back EMF to calibrate the pointer reset position.
These pins interface to the coils of motor 0.
