Enable this feature
Enabling this feature results with all asynchronous message going to the serial interface with a header. Also, during
these asynchronous message transfer S2W Application makes the GPIO19 high. Node Start Up Handling.
Format
The asynchronous message format is as shown:
<ESC><TYPE><SUBTYPE><LENGTH><MESSAGE>
<ESC>
Escape
TYPE
Type of message and the length is one byte. For asynchronous
message, it is 0x41 (ASCII value A)
SUBTYPE

One byte when the value of this byte is one of the values from
0 to E.
Two bytes when the value of this byte is F where the first byte
and the next byte is read and interpreted as per the table in
A.2 Asynchronous & Enhanced Asynchronous Messages, page 512
.
LENGTH
Length of the asynchronous message in hex. This field length is 2
bytes. See
A.2 Asynchronous & Enhanced Asynchronous Messages,
page 512
.
MESSAGE
Exact asynchronous message as string.
