FCEB2 - Frame Decoded Indicator
Each time the SPCA751A has decoded one frame (512 bytes) of data, it changes the state of FCEB2 (either high
to low or low to high) and progresses to the next frame. By counting the number of state-changes, the host processor
is able to know the time elapsed in decoding.
"
Host Command
The host commands consist of 8-bit command and 8-bit ID, totally 16-bit long. (Refer to the SPCA751A
Programming Guide for command definitions) At the falling edges of SCLK1, the SPCA751A checks whether the RFS1
is high. Once it is high, the 16-bit long command is sampled at the following 16 consecutive falling edges of SCLK1
with MSB first. After the LSB is sent, the host processor should send at least one more cycle of SCLK1 to the
SPCA751A.

Host processor writes 512 bytes to the SPCA751A
At the falling edges of SCLK1, the SPCA751A checks whether the RFS1 is high. Once it is high, the 512-byte long
data is sampled at the following 512x8 consecutive falling edges of SCLK1. RFS1 should remain high before the MSB
of the last word. After the LSB of the last word is sent, the host processor should send at least three more cycles of
SCLK1 to the SPCA751A.

* The maximum period of SCLK1 depends on the sampling rate of the decoded data, too long a SCLK1
