FEESWAI — Flash EEPROM Stop in Wait Control
The FEESWAI bit cannot be asserted if the interrupt vector resides in the
Flash EEPROM array.
SVFP — Status V
ERAS — Erase Control
LAT — Latch Control
Freescale Semiconductor, Inc.
This register controls the programming and erasure of the Flash
EEPROM.
SVFP is a read only bit.
This bit can be read anytime or written when ENPE = 0. When set, all
locations in the array will be erased at the same time. The boot block
will be erased only if BOOTP = 0. This bit also affects the result of
attempted array reads. See
ERAS cannot change if ENPE is set.
This bit can be read anytime or written when ENPE = 0. When set, the
Flash EEPROM is configured for programming or erasure and, upon
the next valid write to the array, the address and data will be latched
for the programming sequence. See
on array reads. A high voltage detect circuit on the V
assertion of the LAT bit when the programming voltage is at normal
levels.
