values.
3.2 HTO & RTO - I
Both the Host and the Radio interfaces can 'hang' the RPC2A while it
waits for an external event. Under error conditions the RPC2A will reset
itself if the appropriate HTO or RTO switch is set.
3.3 WE - EEPROM W
This bit protects the EEPROM from accidental writes, it must be set to 1 prior to each byte write to the
EEPROM (addresses 01h to 3Fh). This bit will be cleared by the RPC2A after each byte write.
3.4 ST - S
Writing a 1 to this switch will initiate a radio self test. Both the transmitter and receiver are enabled,
data is feed to the TX and checked for correct recover from the RX. If the test is good, the ST bit will set,
if the test fails the ST bit will not set. The self test takes 20ms to complete.

value
no time out
Time-Out and reset if > 2.9s of plain preamble detected. (note. valid extended
preamble used for wake-ups will not cause a Time-Out to be detected)
no time out
Time-Out and reset if Host fails to reply to any request or handshake
within 2.9s
