6.3.3.2 Channel and Stream Interface Registers
There are two sets of channels to communicate between host and MFC. Each channel has two types of
registers. One is for response from MFC through MFC_SI_RTN_CHID and 15 MFC_COMMON_SI_RG registers.
The other is for command from host through the MFC_SI_CH_INST_ID register and 15
MFC_COMMON_CHx_RG registers.
6.3.3.2.1 Return CH Instance ID Register (MFC_SI_RTN_CHID, R/W, Address = 0xF170_2000)
MFC_SI_RTN_CHID Bit Description Initial State
RTN_CHID [31:0] Return channel instance ID which is used to identify
which channel’s operation is done 0
