PRELIMINARY
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.
17.3.
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.
