Byte Suspend
In master mode, if SPI_CNTRL [19] is set to 1, the hardware will insert a suspend interval 2 ~ 17
serial clock periods between two successive bytes in a transaction word. The byte suspend
setting is the same as the word that using the common bit field of SP_CYCLE register. Note that
when enable the byte suspend function, the setting of TX_BIT_LEN must be programmed as
0x00 only (32 bits per transaction word).
Interrupt
Each SPI controller can generates an individual interrupt when data transfer is finished and the
respective interrupt event flag IF (SPI_CNTRL [16]) will be set. The interrupt event flag will
generates an interrupt to CPU if the interrupt enable bit IE (SPI_CNTRL [17]) is set. The interrupt
event flag IF can be cleared only by writing 1 to it.

Description
Disable both byte reorder function and byte suspend interval.
Enable byte reorder function and insert a byte suspend internal (2~17 SPICLK) among
each byte. The setting of TX_BIT_LEN must be configured as 0x00 ( 32 bits/ word)
Enable byte reorder function but disable byte suspend function.
Disable byte reorder function, but insert a suspend interval (2~17 SPICLK) among each
byte. The setting of TX_BIT_LEN must be configured as 0x00 ( 32 bits/ word)
