Description
7 : UART RI Input (DTE) (Ring Indicate)
8 : UART DCD Input (DTE)
9 : UART DSR Input
10 : UART RI Output (DCE)
11 : UART DCD Output (DCE)
12 : UART DTR Output
13 : UART TX Buffer NOT Empty Output
14 : Input pin – Select Protocol 0=AT,1=MP
15 : Output pin – 0 for AT, 1 for MP
For all UART input/outputs (except 13, 14, & 15) there is
an implied inversion. A logical 1 applies to assert the
output, but by the time it hits the output pin or after it is
read, there is automatic inversion.
When writing to this location(s), validation prevents a write
if the new value is a UART functionality and the same
value already exists in another register. The best
approach to writing to this group of registers is to first
write 0 to all 16 registers and then write new values to all.
New values for these registers only come into effect after
a reset/power cycle.
For details of functionality 13, see section UART Host
Power Saving Facility which describes how this output
can be used to wake a UART host.
Contact the manufacturer for specific mapping and
functionality allocations.

HDP
If set to 0 then an HDP AGENT profile implements;
otherwise with 1, a HDP MANAGER implements.
In addition, bit 2 of Profiles S Reg3 has to be set.
Note: If HDP functionality is not included in the firmware
build, then this register is not available.

HDP
HDP AGENT profile related.
This is the default time in milliseconds an HDP Agent
remains in associated state while there is no activity with
the HDP Manger.
If the value is 0, that is taken as infinite time.
This time is referenced when performing a new HDP
agent IEEE specialization binding with an HDP manager
Bluetooth. In AT mode see command AT+HAB, and in MP
mode see CMD_HDP_BIND
Note: If HDP functionality is not included in the firmware
build, then this register is not available.
