SPP
Reconnect delay when configured as master in auto
connection mode.

SPP/
AT Parser
Specifies the AT Parser mode on connection establishment.
0 = Normal, that data exchanges between UART and RF.
1 = LOCAL_COMMAND. The AT interpreter parses UART
input and RF data is discarded.
2 = REMOTE_COMMAND. The AT interpreter parses RF
input and UART data is discarded. If S Reg 536 is not 1
then this register cannot be set to 2 and an ERROR
returns.
3= LOCAL_COMMAND. The AT interpreter parses UART
input and incoming RF data sends to the host using the
RX<string> asynchronous response.

0
0xFFFF
GPIO
This specifies a write mask when ATS620=X sets multiple
GPIO states.
620
0
0xFFFF
GPIO
ATS620? reads all the GPIO states at once.
ATS620=X writes new GPIO states using the mask in S
Register 619.
621
0
0xFF
AIO
Reads and digitises the voltage on AIO0 and outputs it as
an 8 bit number on the terminal program.
622
0
0xFF
AIO
Reads and digitises the voltage on AIO1 and outputs it as
