GO_BUSY
TX_BIT_LEN = 0x01 … 1 bit
TX_BIT_LEN = 0x02 … 2 bits

TX_BIT_LEN = 0x1F … 31 bits
TX_BIT_LEN = 0x00 … 32 bits
Transmit At Negative Edge
1 = The transmitted data output signal is changed at the falling edge of SPICLK
0 = The transmitted data output signal is changed at the rising edge of SPICLK
Receive At Negative Edge
1 = The received data input signal is latched at the falling edge of SPICLK
0 = The received data input signal is latched at the rising edge of SPICLK
Go and Busy Status
1 = In master mode, writing 1 to this bit to start the SPI data transfer; in slave mode,
0 = Writing 0 to this bit to stop data transfer if SPI is transferring.
During the data transfer, this bit keeps the value of 1. As the transfer is finished, this bit
will be cleared automatically.
Note: All registers should be set before writing 1 to this GO_BUSY bit. When a transfer
is in progress, writing to any register of the SPI/MICROWIRE master/slave core has no
effect.
writing 1 to this bit indicates that the slave is ready to communicate with a master.
