In general, K-series MCUs have 768 bytes RAM, 640 bytes EEPROM, and 24 Kbytes ROM/EPROM.
Some devices in the series have portions of their memory resources disabled. Some have ROM and
some have EPROM replacing ROM. The following paragraphs describe the memory systems of devices
in the series.
The INIT, INIT2, and CONFIG registers control the presence and location of the registers, RAM, EE-
PROM, and ROM/EPROM in the 64 Kbyte CPU address space. The 128-byte register block originates
at $0000 after reset and can be placed at any 4 Kbyte boundary ($x000) after reset by writing an ap-
propriate value to the INIT register. Refer to Figure 4.
NOTE: ROM/EPROM can be enabled in special test mode by setting ROMON bit in the config register after reset.
