Description

CBEIE

Command Buffer Empty Interrupt Enable — The CBEIE bit enables an interrupt in case of an empty command

buffer in the EEPROM module.

0 Command Buffer Empty interrupt disabled.

1 An interrupt will be requested whenever the CBEIF ﬂag (see Section 26.3.2.6, “EEPROM Status Register

(ESTAT)”) is set.

CCIE

Command Complete Interrupt Enable — The CCIE bit enables an interrupt in case all commands have been

completed in the EEPROM module.

0 Command Complete interrupt disabled.

1 An interrupt will be requested whenever the CCIF ﬂag (see Section 26.3.2.6, “EEPROM Status Register

(ESTAT)”) is set.
