A.4.3 Register Array Write Operation
A write operation is completed through the transfer of a 16-bit value using the SPI as shown in the diagram below. Data present
at the D
Contents of the register at the time the write operation is initiated are presented at the D
edges of the CLK input.
A.4.4 Internal Address Map Overview
OTP data is transferred to internal registers during the first sixteen clock cycles following oscillator startup and negation of internal
reset. When the device operates in test mode, OTP data in the mirror registers may be overwritten. Mirror register writes must
be enabled by setting the SPI_WRITE_ENABLE bit (address $29[5]). This bit may be set by writing the value $0 to address $20.
Internal register read and write operations are described in
