27.4.10.5 Erase Flash Sector Command
The Erase Flash Sector operation erases all addresses in a flash sector.

1. Must be longword aligned (flash address [1:0] = 00).
After clearing CCIF to launch the Erase Flash Sector command, the flash memory
module erases the selected program flash sector and then verifies that it is erased. The
Erase Flash Sector command aborts if the selected sector is protected (see the description
of the FPROT registers). If the erase-verify fails the FSTAT[MGSTAT0] bit is set. The
CCIF flag is set after the Erase Flash Sector operation completes. The Erase Flash Sector
command is suspendable (see the FCNFG[ERSSUSP] bit and Figure 27-26).

27.4.10.5.1 Suspending an Erase Flash Sector Operation
To suspend an Erase Flash Sector operation set the FCNFG[ERSSUSP] bit (see Flash
Configuration Field Description) when CCIF is clear and the CCOB command field holds
the code for the Erase Flash Sector command. During the Erase Flash Sector operation
(see Erase Flash Sector Command), the flash memory module samples the state of the
ERSSUSP bit at convenient points. If the flash memory module detects that the
