CBEIF — Command Buffer Empty Interrupt Flag
CCIF — Command Complete Interrupt Flag
PVIOL — Protection Violation Flag
ACCERR — Access Error Flag
The CBEIF flag indicates that the command buffer for the interleaved
FLASH physical blocks selected by BKSEL[1:0] is empty and that a
new command sequence can be started. Clear CBEIF by writing it
to 1. Writing a 0 to CBEIF has no effect but can be used to abort a
command sequence. The CBEIF bit can trigger an interrupt request if
the CBEIE bit is set in SGFMMCR. While CBEIF is clear, the
SGFMCMD register is not writable.
The CCIF flag indicates that no commands are pending for the
FLASH physical blocks selected by BKSEL[1:0]. CCIF is set and
cleared automatically upon start and completion of a command.
Writing to CCIF has no effect. The CCIF bit can trigger an interrupt
request if the CCIE bit is set in SGFMCR.
The PVIOL flag indicates an attempt was made to initiate a program
or erase operation in a FLASH logical sector denoted as protected by
SGFMPROT. Clear PVIOL by writing it to 1. Writing a 0 to PVIOL has
no effect. While PVIOL is set in any banked register, it is not possible
to launch another command.
The ACCERR flag indicates an illegal access to the SGFM array or
registers caused by a bad program or erase sequence. ACCERR is
cleared by writing it to 1. Writing a 0 to ACCERR has no effect. While
ACCERR is set in any banked register, it is not possible to launch
another command. See
