• Manufacturer Part Number: mc9s12vr48
• Description: S12 Microcontrollers
• Manufacturer: Freescale Semiconductor, Inc

EEPROM Sector — The EEPROM sector is the smallest portion of the EEPROM memory that can be
erased. The EEPROM sector consists of 4 bytes.
NVM Command Mode — An NVM mode using the CPU to setup the FCCOB register to pass parameters
required for Flash command execution.
Phrase — An aligned group of four 16-bit words within the P-Flash memory. Each phrase includes two
sets of aligned double words with each set including 7 ECC bits for single bit fault correction and double
bit fault detection within each double word.
P-Flash Memory — The P-Flash memory constitutes the main nonvolatile memory store for applications.
P-Flash Sector — The P-Flash sector is the smallest portion of the P-Flash memory that can be erased.
Each P-Flash sector contains 512 bytes.
Program IFR — Nonvolatile information register located in the P-Flash block that contains the Version
ID, and the Program Once field.
