24 ; With the following EQU statements the initialization of memory
25 ; at processor reset can be defined:

27 ; IDATALEN: IDATA memory size <0x0-0x100>
28 ; Note: The absolute start-address of IDATA memory is always 0
29 ; The IDATA space overlaps physically the DATA and BIT areas.
0080 30 IDATALEN EQU 80H
