4.5.10
Only half of the EEPROM is in the memory map. The EPGSEL bit in FCNFG register selects which half
of the array can be accessed in foreground while the other half can not be accessed in background. There
are two mapping mode options that can be selected to configure the 8-byte EEPROM sectors: 4-byte mode
and 8-byte mode. Each mode is selected by the EPGMOD bit in the FOPT register.
In 4-byte sector mode (EPGMOD = 0), each 8-byte sector splits four bytes on foreground and four bytes
on background but on the same addresses. The EPGSEL bit selects which four bytes can be accessed.
During a sector erase, the entire 8-byte sector (four bytes in foreground and four bytes in background) is
erased.
In 8-byte sector mode (EPGMOD = 1), each entire 8-byte sector is in a single page. The EPGSEL bit
selects which sectors are on background. During a sector erase, the entire 8-byte sector in foreground is
erased.
4.5.11
The FLASH and EEPROM module has seven 8-bit registers in the high-page register space and three
locations in the nonvolatile register space in FLASH memory. Two of those locations are copied into two
corresponding high-page control registers at reset. There is also an 8-byte comparison key in FLASH
memory. Refer to
EEPROM registers. This section refers to registers and control bits only by their names. A Freescale
Semiconductor-provided equate or header file normally is used to translate these names into the
appropriate absolute addresses.
4.5.11.1
Before any erase or programming operations are possible, write to this register to set the frequency of the
clock for the nonvolatile memory system within acceptable limits. Bit 7 is a read-only flag and bits 0 to 6
may be read at any time but can be written only one time after reset.
