microprocessor interface downloads the filter coefficients and the delay
value for proper FIFO initialization.
The microprocessor interface uses an I
protocol. The interface is slave-only and can not be a master to the serial
bus. The base address of the component is composed of a fixed five-bit
address and two selectable bits, which are fed through SB_BASE[1:0].
The L64777 supports:
