Bit 7 CFWEN: Flash Memory Erase/Write function enable control
0: Flash memory erase/write function is disabled
1: Flash memory erase/write function has been successfully enabled
When this bit is cleared to 0 by application program, the Flash memory erase/write
function is disabled. Note that this bit cannot be set high by application programs.
Writing a "1" into this bit will result in no action. This bit is used to indicate the Flash
memory erase/write function status. When this bit is set high by the hardware, it means
that the Flash memory erase/write function is enabled successfully. Otherwise, the
