7.6 User-accessible data array

A user-accessible data array allows each device to be customized. The array consists of a one time

programmable (OTP) factory-programmable block, an OTP user-programmable block, and read-only registers

for data and device status. The OTP blocks incorporate independent data verification. In order to perform the

OTP, a custom platform is typically used prior to PCB assembly since the VPP voltage required is much higher

than the nominal supply as shown in Table 103. See application note AN12727[3].
