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.
