Figure 6-11. CFM User Status Register (CFMUSTAT)
Command buffer empty interrupt flag. The CBEIF flag indicates that the command
buffer for the interleaved Flash physical blocks 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 CFMMCR. While CBEIF is clear, the
CFMCMD register is not writable.
1 Command buffer is ready to accept a new command.
0 Command buffer is full.
Command complete interrupt flag. The CCIF flag indicates that no commands are
pending for the Flash physical blocks. 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 CFMCR.
1 All commands are completed
0 Command in progress
Protection violation flag. The PVIOL flag indicates an attempt was made to initiate
a program or erase operation in a Flash logical sector denoted as protected by
CFMPROT. Clear PVIOL by writing it to 1. Writing a 0 to PVIOL has no effect. While
PVIOL is set in any this register, it is not possible to launch another command.
1 A protection violation has occurred
0
Access error flag. The ACCERR flag indicates an illegal access to the CFM 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 this
register, it is not possible to launch another command. See
