Serial Data Register (SRL: $006, SRU: $007):
The serial data register configuration is shown in figures
72 and 73. This register has the following functions.
Transmission data write and shift
Receive data shift and read
Writing data in this register is output from the SO pin, LSB first, synchronously with the falling edge of the
transmit clock; data is input, LSB first, through the SI pin at the rising edge of the transmit clock.
Input/output timing is shown in figure 74.
Data cannot be read or written during serial data transfer. If a read/write occurs during transfer, the
accuracy of the resultant data cannot be guaranteed.
