Host Read Byte Count (H_RBC). This bit is used for Host Continue Read Mode which is
determine the number of data byte host should read and then generate a NOT ACK. This
register is only available when H_CONTRD set to 1.
Host/Slave Data FIFO Register (HS_DATAFIFO).
This is a 16-bytes data FIFO for Host/Master/Slave transmit and receive. During the
host/master mode, when a sequential 8-bit data fills into this data FIFO register, the data
are also sequent printing out on SMBus.
In the Slave-transmit mode, the SMBus will hold CLK low until each returned data byte
written to FIFO. This feature will be disabled in Slave-receive mode during the NOT ACK
receive operation.
Host-Slave Address Register (HS_ADDR). When the host serves as slave mode, this
register should be compared. If the external master transmits the address matched this
register, the host will be ready to receive or transmit data.
Reserved for general call.
