Controller
State 13: A header, or its complement, has been received. Data and clock signals are output on the SPI port
until EOM indicates the end of the data sequence. If the complement of the header has been received,
output data are complemented also.
When an EOM occurs before the current byte is fully shifted out, dummy bits are inserted until the number
of shifted bits is a multiple of 8.
For all states: At any time, a low level applied to STROBE forces the circuit to state 10, and a low level
applied on CONFB forces the state machine to state 1.
