PROGRAMMING MODE VIA PSI5
Introduction
Programming Mode Via PSI5 Entry
• The device is unlocked (the LOCK_U bit in the DEVCFG2 register is ‘0’).
• At least 31 sync pulses are detected, directly preceding the Programming Mode Entry Short Command during the
• Programming Mode Entry is blocked until the device is Reset.
• The device proceeds with PSI5 Initialization Phase 2, and PSI5 Initialization Phase 3.
• The device enters normal mode, and responds as programmed to normal sync pulses.
• Normal transmissions to sync pulses are terminated.
• After a pre-defined Start Delay, the device begins to decode PSI5 Short and Long Commands.
• The device responds only to valid PSI5 Short and Long Commands addressed to Sensor Address ‘001’, as
