FT
Flow Control Threshold
. The UART flow control threshold. De-
assert CTS and/or send XOFF when FT bytes are in the UART
receive buffer. Re-assert CTS when less than FT - 16 bytes are in
the UART receive buffer.
0x11 - 0x94F
0x91F
AP
API Mode
. The serial API mode. The following settings are
allowed:
0
Transparent mode, API mode is off. All serial input and output
is raw data and packets are delineated using the RO and RB
parameters.
1
API mode without escapes is on. All UART input and output
data is packetized in the API format.
2
API mode is on with escaped sequences inserted to allow for

to be passed as data).

. The API data frame output format for received
frames. This parameter applies to both the UART and SPI
interfaces.
