Freescale Semiconductor
NOTE
For the MCU, the SPI clock format is the clock phase control bit CPHA = 0
and the clock polarity control bit CPOL = 0.
3. Master Out/Slave In (MOSI) - Incoming data from the host is presented on the MOSI input.
4. Master In/Slave Out (MISO) - The 802.15.4 modem presents data to the master on the MISO
output.
Although the SPI port is fully static, internal memory, timer and interrupt arbiters require an internal clock
(CLKcore), derived from the crystal reference oscillator, to communicate from the SPI registers to internal
registers and memory.
4.6.2.1
SPI Burst Operation
The SPI port of the 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 802.15.4 modem transaction is three or more SPI bursts long, the
timing of a single SPI burst is shown in Figure 10. The maximum SPI clock rate is 8 Mhz from the MCU
because the modem is limited by this number.
