Figure 7. On-Chip Registers
Programmable Address Decoding
The X88C75 features an internal programmable ad-
dress decoder which allows the nonvolatile memory
array and the internal registers to be mapped in various
locations of the 64K-byte memory map. The register set
is mappable into a 1K-byte block, while the nonvolatile
memory array is mappable into an 8K-byte block. The
mapping is controlled by two nonvolatile configuration
registers, the SFR Map Register and the E

Memory
Map Register. Their bits are mapped as follows:

The A15-A10 are upper address bits for the 1K-byte
page where the SFR memory is mapped.

NOTE: * The value returned by reading these registers is the complement of the
actual data. These registers are nonvolatile and a special SDP sequence
is used to alter their contents. All the other registers are initialized by a
valid reset input signal and when the device is power cycled.
