When set to 1, a remote device can capture the AT parser of this unit
by it sending this module an escape “!!!” sequence. The inter
character timing is set via S Register 12.
If S Register 507 is >/= 2, then reading this register always returns 0
and writing 1 results in ERROR 33.

This register is no longer available – See 551,552, and 553 instead.
It only exists in firmware version 1.1.12 to 1.1.47
The functionality it controlled is now defined by registers 551,552,
and 553

If 1, then when a successful pairing occurs, it is automatically saved
in the trusted device database, if the database has room to store it.

When set to 1, in idle mode (S512=1), UART Rx characters are
discarded if DSR is deasserted.

Sets the MTU in L2CAP configuration negotiations. The value of 0 is
a special value which means that the current value should remain.

This sets the power level in dBm when inquiring or paging. Reading
this register returns the value stored in non-volatile memory.

As per S541, however reading this register returns the current power
level as set in the base band. The read can be different from
S541because the actual power is set using a lookup table and the
base band rounds down to the nearest value in the table.

If this is set to 1, then incoming pairing attempts are accepted (if a pin
code has been pre-entered using AT+BTK) while in the wait phase of
auto connect cycle initiated by the AT+BTR command. In addition to
accepting pairing attempts, if the pairing is successful, then the new
device is automatically set as the peer address for automatic
connections (as if an explicit AT+BTR command was entered).
See S Register 505 and 530.

Configure the UART for either low latency or maximum throughput. A
setting of 1 gives maximum throughput.
