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.
00 for first configuration data block.
Pin INH mode. Mode will be changed after PxReq or PxResp
Receive data length. Message PxReq contains two data
bytes if RxDL = 0 and three data bytes if RxDL = 1.
Analog source channel selection. The number of ADCIN[2:0]
determines which of the P7 to P0 input is used. For example
if ADCIN[2:0] = 101 then P5 will be the input. ADCIN[2:0] is
used only if ADC mode is selected (IM[1:0] = 01) and
RxDL = 0 (No analog input selection at PxReq).
High-side enable for I/O pin Px.
Low-side enable for I/O pin Px.
Output mode for I/O pin Px.
