NOTES:
A. While the data is being read through the serial-data register, TRG\ is a don’t care; however, TRG\ must be held high when RAS\ goes low.
This is to avoid the initiation of a register-data transfer operation.
B. The serial data-out cycle is used to read data out of the data registers. Before data can be read via SQ, the device must be put into the
read mode by performing a transfer-read cycle.
