A typical interconnection to a microcontroller is shown in
Although the SPI port is fully static, internal memory, timer and interrupt arbiters require an internal clock
(CLK
registers and memory.
6.2.1
The SPI port of an MCU transfers data in bursts of 8 bits with most significant bit (MSB) first. The master
(MCU) can send a byte to the slave (transceiver) on the MOSI line and the slave can send a byte to the
master on the MISO line. Although an MC13202 transaction is three or more SPI bursts long, the timing
of a single SPI burst is shown in
SPI digital timing specifications are shown in
