Table 27 OTP Memory Control

14.5 OTP / ICE INTERRUPTS

The OTP and ICE memories are associated with two Interrupt event flags.

The OTP_CMD_END_EINT interrupt is set each time an OTP / ICE Command has completed or if

OTP Auto-Program has completed. (See Section 14.4 for a definition of the OTP and ICE

Commands. See Section 14.6.3 for details of the OTP Auto-Program function.)

The OTP_ERR_EINT interrupt is set when an OTP / ICE Error has occurred. The errors detected

include ICE Read Failure, OTP Verify Failure and attempted OTP Write to a page that has been

‘Finalised’.

Each of these secondary interrupts triggers a primary OTP Memory Interrupt, OTP_INT (see

Section 23). This can be masked by setting the mask bit(s) as described in Table 75.
