Description
Slave node address (NAD). NAD values are in the range
from 1 to 127, while 0 and 128 to 255 are reserved for other
purposes. The slave node address is assigned with the
assign NAD command (see
Protocol control information.
Service identifier. As SlaveResp the RSID value will be
0xF4.
01 for the second configuration data block.
Limp home sleep mode. If LSLP = 1, the Limp home sleep
mode is enabled. In this case the Limp Home value (LH) is
automatically used as output value if the Sleep mode is
entered.
Transmit data length. Message PxResp contains two data
bytes if TxDL = 0 and four data bytes if TxDL = 1.
Switch matrix capture. If SMC = 1, the Switch matrix
capture mode is enabled.
Switch matrix wake-up. If SMW = 1, the switch matrix
wakes up upon changed input level.
Switch matrix enable
Unassigned pins can be used as I/O. It should be noted,
however, that for the unassigned pins, which are configured
in Capture mode, the captured edge value will not be
transferred.
