14.5.1 Master Mode
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
NOTE:
The SPI operates in master mode when the SPI master bit, SPMSTR, is
set.
Configure the SPI modules as master or slave before enabling them.
Enable the master SPI before enabling the slave SPI. Disable the slave
SPI before disabling the master SPI. (See
Register.)
Only a master SPI module can initiate transmissions. Software begins
the transmission from a master SPI module by writing to the transmit
data register. If the shift register is empty, the byte immediately transfers
to the shift register, setting the SPI transmitter empty bit, SPTE. The byte
begins shifting out on the MOSI pin under the control of the serial clock.
