MCM_PLACR field descriptions (continued)
Field
Description
When software needs to access the flash memory while a flash memory resource is being manipulated by
a flash command, software can enable a stall mechanism to avoid a read collision. The stall mechanism
allows software to execute code from the same block on which flash operations are being performed.
However, software must ensure the sector the flash operations are being performed on is not the same
sector from which the code is executing.
ESFC enables the stall mechanism. This bit must be set only just before the flash operation is executed
and must be cleared when the operation completes.
