Time t1 in the figure above does not have to be any specific time, just so
long as the SER_IO line goes high before the CRT/LRN line. Time t2 should
be greater than 120S (typical of 35mS, see the Mode Entry Timings
section) to ensure that the transcoder goes into Serial Mode. There is not a
maximum time specified. Once in Serial Mode, the transcoder waits for the
start byte (0x00) of the serial command.
The timings associated with each command and the transcoder’s response
are listed in Tables 7 (9,600bps) and 8 (28,800bps).
To send consecutive commands, keep the CRT/LRN line high and take the
SER_IO line high within 50S of the MODE_IND line going low.
It should be noted that all of the settings are written into non-volatile
memory, so they will be retained if power is removed from the chip. This
includes all values, such as custom byte and target address, as well as the
enabled / disabled states.
