MC9S08GB/GT

Section 12 Serial Peripheral Interface (SPI) Module

The MC9S08GB/GT provides one serial peripheral interface (SPI) module. The four pins associated with

SPI functionality are shared with port E pins 2–5. See the Electrical Characteristics appendix for SPI

electrical parametric information. When the SPI is enabled, the direction of pins is controlled by module

configuration. If the SPI is disabled, all four pins can be used as general-purpose I/O.

NOTES:

1. Port pins are software configurable with pullup device if input port.

2. Pin contains software configurable pullup/pulldown device if IRQ enabled (IRQPE = 1).

3. IRQ does not have a clamp diode to VDD. IRQ should not be driven above VDD.

4. Pin contains integrated pullup device.

5. High current drive

6. Pins PTA[7:4] contain software configurable pullup/pulldown device. Pulldown available when KBI enabled (KBIPn = 1).
