MOTOROLA
SGFM — Second generation FLASH for M•CORE. Acronym used
throughout this document to reference this module.
SGFM Module — Includes the bus interface, command controller,
built-in self test (BIST) controller, and the FLASH physical blocks.
FLASH Physical Block — A 64-Kbyte FLASH hard block organized as
32,768 halfwords (32K x 16 bits) that includes high voltage generation
and parametric test features.
FLASH Logical Sector — An 8-Kbyte sector of contiguous FLASH
memory that can be protected from program and erase operations. A
logical sector can have supervisor/user and program/data space access
restrictions.
FLASH Erase Page — Eight rows of 64 bytes (512 bytes) in one FLASH
physical block. Two pages, one from each interleaving physical block,
are erased at one time.
Banked Register — A register that operates on two interleaved FLASH
physical blocks. Banked registers share the same control register
addresses as the equivalent registers for the other FLASH physical
blocks. The active register bank is selected by a bank select field in the
unbanked register space. The SGFM module contains one to four sets
of banked registers depending on the size of the array.
Unbanked Register — A register which operates upon all FLASH
physical blocks.
Command Sequence — A three step sequence to program, erase, or
verify the FLASH.
FLASH User Mode — The mode in which the FLASH module operates
when executing user code and software controlled program and erase
operations.
SATO — Acronym used for sense amplifier timeout analog hard-macro
block. The SATO saves power at low system clock frequencies by
limiting the time during which sense amps are enabled.
Erased State — Bit state that reads as a 1.
Programmed State — Bit state that reads as a 0.
