the SPSR. In master mode the SS pin can be selected to be a general-purpose output (when configured
as an MC68HC05C9A) by writing a 1 in bit 5 of the port D data direction register, thus disabling the mode
fault circuit.
When CPHA = 0, the shift clock is the OR of SS with SCK. In this clock phase mode, SS must go high
between successive characters in an SPI message. When CPHA = 1, SS may be left low for several SPI
characters. In cases where there is only one SPI slave MCU, its SS line could be tied to VSS as long as
CPHA = 1 clock modes are used.
10.4 Functional Description
Figure 10-2 shows a block diagram of the serial peripheral interface circuitry. When a master device
transmits data to a slave via the MOSI line, the slave device responds by sending data to the master
device via the master’s MISO line. This implies full duplex transmission with both data out and data in
synchronized with the same clock signal. Thus, the byte transmitted is replaced by the byte received and
eliminates the need for separate transmit-empty and receive-full status bits. A single status bit (SPIF) is
used to signify that the I/O operation has been completed.
