Table 4.1: BTM - General S Registers
Description
Disconnect timeout in seconds. This timer specifies how long to
wait for confirmation from the peer device and/or the underlying
stack that the connection has been successfully torn down. There
can be instances where a confirmation does not arrive and so in
this case this timer is used to ‘close off’ the procedure and put the
state machine back into a proper mode for new operations.
Time is specified with 15 seconds intervals.
Sniff Attempt Time in units of milliseconds. 0 means disable.
See Section 7, pg. 40 and Figure 3.8.
Sniff Timeout Time in units of milliseconds. 0 means disable.
See Section 7, pg. 40 and Figure 3.8.
Sniff Minimum Interval in units of milliseconds. 0 means disable.
See Section 7, pg. 40 and Figure 3.8.
Sniff Maximum Interval in units of milliseconds. 0 means disable.
See Section 7, pg. 40 and Figure 3.8.
If set to 1, RI (Ring Indicate) line is configured as an input and
forces the start-up mode (SReg512) and post-timeout on Start-up
mode (SReg555) to be dependent on the state of RI. The RI condi-
tional modes are defined by S Registers 566 to 569 inclusive.
If S565=1, and RI is asserted then this is the mode the device will
start up in.
If S565=1, and RI is de-asserted then this is the mode the device
will start up in.
If S565=1, and RI is asserted then this is the mode the device
will assume after the post-start-up timeout defined in SReg 554
instead of mode defined in SReg555
If S565=1, and RI is de-asserted then this is the mode the device
will assume after the post-start-up timeout defined in SReg 554
instead of mode defined in SReg555
Enable/Disable eSCO
After a disconnection, there will be a cold reset
Set this to 1 to reduce the trusted device database to just 1 record
when auto saving of pairing is enabled via S reg 538

10 General Purpose 32 bit Registers for use by host. These are
stored in non-volatile memory.
