PRODUCTION DATA.
This section applies only to the DRV8340-Q1 SPI devices.
NOTE
Do not modify reserved registers or addresses not listed in the register map (). Writing to these registers may have unintended effects. For all reserved bits, the default value is 0. To help prevent erroneous SPI writes from the master controller, set the LOCK bits to lock the SPI registers.
