16-Bit Serial Peripheral Interface (S08SPI16V1)
15.1
Introduction
The 8- or 16-bit selectable serial peripheral interface (SPI) module provides for full-duplex, synchronous,
serial communication between the MCU and peripheral devices. These peripheral devices can include
other microcontrollers, analog-to-digital converters, shift registers, sensors, memories, etc.
The SPI runs at a baud rate up to the bus clock divided by two in master mode and up to the bus clock
divided by four in slave mode. Software can poll the status flags, or SPI operation can be interrupt driven.
The SPI also supports a data length of 8 or 16 bits and includes a hardware match feature for the receive
data buffer.
The MC9S08JM60 series have two serial peripheral interface modules (SPI1 and SPI2). The four pins
associated with SPI functionality are shared with PTB[3:0] and PTE[7:4]. See
Appendix A, “Electrical
Characteristics,” for SPI electrical parametric information.
15.1.1
SPI Port Configuration Information
By default, the input filters on the SPI port pins will be enabled (SPIxFE=1), which restricts the SPI data
rate to 6 MHz, but protects the SPI from noise during data transfers.To configure the SPI at a baud rate of
6MHz or greater, the input filters on the SPI port pins must be disabled by clearing the SPIxFE in SOPT2.
and also enable the high output drive strength selection on the affected SPI port pins.
