12.2 External Signal Description
12.2.1 SLCTx — SLIC Transmit Pin
The SLCTx pin serves as the serial output of the SLIC module.
12.2.2 SLCRx — SLIC Receive Pin
The SLCRx pin serves as the serial input of the SLIC module. This input feeds into the digital receive filter
block which filters out noise glitches from the incoming data stream.
12.3 Register Definition
12.3.1 SLIC Control Register 1 (SLCC1)
SLIC control register 1 (SLCC1) contains bits used to control various basic features of the SLIC module,
including features used for initialization and at runtime.
