28.4.10.4 Allowed Simultaneous Flash Operations
Only the operations marked 'OK' in the following table are permitted to run
simultaneously on the program flash, data flash, and FlexRAM memories. Some
operations cannot be executed simultaneously because certain hardware resources are
shared by the memories. The priority has been placed on permitting program flash reads
while program and erase operations execute on the FlexNVM and FlexRAM. This
provides read (program flash) while write (FlexNVM, FlexRAM) functionality.
For devices containing FlexNVM:

1. When FlexRAM configured for EEPROM (writes are effectively multi-cycle operations).
2. When FlexRAM configured as traditional RAM (writes are single-cycle operations).
3. When FlexRAM configured as traditional RAM, writes to the RAM are ignored while the Program Section command is
active (CCIF = 0).
