disable parity bit in S2B mode
enable parity bit in S2B mode
S2B transmission mode
SPI transmission mode
SPI clock active LOW; S2B even parity
SPI clock active HIGH; S2B odd parity
comsync pin level
syssync pin level
inverted comsync pin level
inverted syssync pin level
transmit data buffer is empty and ready for another byte
receive data buffer is not valid
receive data buffer is valid
a byte was lost because the ‘rxdata’ register was not read in time
received parity bit is in error
comiack pin level
transmit register is full (a byte is being sent)
receive register holds a byte, need to read a byte immediately to avoid overrun
