To execute a read cycle, the host must first verify that the CMD register (at 00

02
Finally, the read cycle is triggered by setting the RD bit (bit 0) in the CMD register.
When the internal operation is finished, the embedded controller updates the 32-bit DAT
register (at 04
ADDR register and subtracted from the CNT register.
The embedded controller then clears the CMD register to 0. After the host polls the CMD
register to confirm that it is cleared to 00
Data is loaded to the DAT register one byte at a time, LSB first, regardless of the internal
address from which the bytes are read. Up to four bytes are fetched in each read cycle,
even if the CNT register specifies more than four. To invoke a new read cycle that
fetches up to four more bytes of data, the host must set the RD bit in the CMD register
again. This process continues until CNT reaches zero.
