LOGIC COMMANDS AND REGISTERS
LOGIC COMMANDS AND REGISTERS
This IC is One Time Programmable (OTP), during the final
test phase, in the factory. The OTP Programmable Options
table (Table 6) describes the programmable functions that
are selectable by the customer. These Non-volatile Memory
(NVM) bits are not alterable after the OTP operation at the
factory.

Notes
15. These are adjustable independently, the IC internally compensates for the pole-pairs if the correct OTP setting is made. Frequency
measurements are made over multiple cycles (8) for greater accuracy.
