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. Both settings of byte
suspend and word suspend are configured in SP_CYCLE. Note that when enable the byte
suspend function, the setting of TX_BIT_LEN must be programmed as 0x00 only (32-bit per
transaction word).
No Slave Select Mode (3-WIRE Mode)
This is used to ignore the slave select signal in slave mode. The SPI controller can work on no
slave select mode (3-WIRE mode) interface including SPICLK, SPI_MISO, and SPI_MOSI when
it is set as a slave device. When the NOSLVSEL bit is set as 1, the controller will start to
transmit/receive data after the GO_BUSY bit is set to 1 and the serial clock appears. In no slave
select signal mode, the SS_LTRIG, SPI_SSR[4], shall be set as 1.

NuMicro™ NUC130/NUC140 Technical Reference Manual
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)
