Data Memory Address Space
The Flash information area, including Zilog Flash option bits, are located in the data mem-
ory address space. The Z8 Encore! MCU is configured by these proprietary Flash option
bits to prevent the user from writing to the eZ8 CPU data memory address space.
Flash Information Area
The Flash information area is physically separate from program memory and is mapped to
the address range FE00H to FE7FH. Not all of these addresses are user-accessible. Factory
trim values for the VBO, Internal Precision Oscillator and factory calibration data for the
ADC are stored here.
Table 70 describes the Flash information area. This 128-byte information area is accessed
by setting the bit 7 of the Flash Page Select Register to 1. When access is enabled, the
