HiSPi Protocol Layer

The HiSPi protocol is described the HiSPi Protocol

Specification document.

Serial Configuration

The serial format should be configured using R0x31AC.

Refer to the AR0331 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

• 0x0301 − Sensor supports single-lane HiSPi operation
