in an “off-line” state.
In a multiple-master environment, the system controller should check the state of the
SLVSEL flag (SPI0CN.2) to ensure the bus is free before setting the MSTEN bit and initiating a data transfer.

Serial Clock Timing
As shown in Figure 17.4, four combinations of serial clock phase and polarity can be selected using the clock
control bits in the SPI Configuration Register (SPI0CFG). The CKPHA bit (SPI0CFG.7) selects one of two clock
phases (edge used to latch the data). The CKPOL bit (SPI0CFG.6) selects between an active-high or active-low
clock. Both master and slave devices must be configured to use the same clock phase and polarity. Note: the SPI
should be disabled (by clearing the SPIEN bit, SPI0CN.0) while changing the clock phase and polarity.
The SPI Clock Rate Register (SPI0CKR) as shown in Figure 17.7 controls the master mode serial clock frequency.
This register is ignored when operating in slave mode.
