HiSPi Protocol Layer

The HiSPi protocol is described in the HiSPi Protocol

Specification document.

Serial Configuration

The serial format should be configured using R0x31AC.

Refer to the AR0141CS Register Reference document for

more detail regarding this register.

The serial_format register (R0x31AE) controls which

serial format is in use when the serial interface is enabled

(reset_register[12] = 0). The following serial formats are

supported:

• 0x0304 − Sensor supports quad−lane HiSPi operation

• 0x0302 − Sensor supports dual−lane HiSPi operation
