12 / 56 page  Sensor 12 Freescale Semiconductor, Inc. MMA65xx 3 Functional Description 3.1 Customer Accessible Data Array A customer accessible data array allows for each device to be customized. The array consists of an OTP factory programma- ble block and read/write registers for device programmability and status. The OTP and writable register blocks incorporate inde- pendent CRC circuitry for fault detection (reference Section 3.2). The writable register block includes a locking mechanism to prevent unintended changes during normal operation. Portions of the array are reserved for factory-programmed trim values. The customer accessible data is shown in the table below. Type codes F: Factory programmed OTP location R/W: Read/write register R: Read-only register N/A: Not applicable Table 3.
