24.1.3 Glossary
Command write sequence — A series of MCU writes to the flash FCCOB register
group that initiates and controls the execution of flash algorithms that are built into the
flash memory module.
Endurance — The number of times that a flash memory location can be erased and
reprogrammed.
FCCOB (Flash Common Command Object) — A group of flash registers that are used
to pass command, address, data, and any associated parameters to the memory controller
in the flash memory module.
Flash block — A macro within the flash memory module which provides the nonvolatile
memory storage.
Flash Memory Module — All flash blocks plus a flash management unit providing
high-level control and an interface to MCU buses.
HSRUN — An MCU power mode enabling high-speed access to the memory resources
in the flash module. The user has no access to the flash command set when the MCU is in
HSRUN mode.
