1.5 REGISTER & MEMORY MAP
As shown in the
Table 1
, the MCU is capable of
addressing 64K bytes of memories and I/O regis-
ters. In this MCU, 63742 of these bytes are user
accessible.
The available memory locations consist of 128
bytes of I/O registers, 256 bytes of RAM, 128
bytes of EEPROM and 16Kbytes of user EPROM/
ROM. The RAM space includes 64bytes for the
stack from 0140h to 017Fh.
The highest address bytes contain the user reset
and interrupt vectors.
