Motor Control Flash MCUs
The Z8FMC16100 Series Flash MCU products contain 16 KB of on-chip Flash memory in
the Program Memory address space, depending upon the device (FMC08100 has 8 KB
and FMC04100 has 4 KB). Reading from Program Memory addresses outside the avail-
able Flash memory addresses returns
Memory addresses produces no effect. Table 3 describes the Program Memory Maps for
the Z8FMC16100 Series Flash MCU products.
Table 3. Z8FMC16100 Series Flash MCU Program Memory Maps
The Z8FMC16100 Series Flash MCU does not use the eZ8 CPU’s 64KB Data Memory
address space.
Table 4 describes the Z8FMC16100 Series Flash MCU Information Area. This 512-byte
Information Area is accessed by setting bit 7 of the Flash Page Select Register to 1. When
access is enabled, the Information Area is mapped into the Program Memory and overlays
the 512 bytes at addresses
execution of LDC and LDCI instruction from these Program Memory addresses return the
Information Area data rather than the Program Memory data. Reads of these addresses
through the On-Chip Debugger also returns the Information Area data. Execution of code
from these addresses continues to correctly use the Program Memory. Access to the Infor-
mation Area is read-only.
