25 | |
26 ;First Bank of Custom Functions: | |
27 ; The custom functions are stored in the internal EEPROM after 0x80 | |
28 ; any custom function occupies 4 byte: | |
29 ; 2 byte (low:high) store the default value, reset from menu "reset" | |
30 ; if bit16=1 then the custrom function is 15bit value, if not it's a 8bit value | |
31 ; 2 byte (low:high) store the actual value | |
32 ; defaults for custom functions are in menu "reset" | |
33 ; get values with GETCUSTOM8 .x with x=0...32 for 8 Bit values (stored in WREG) | |
34 ; or with GETCUSTOM15 .x with x=0...32 for 15 Bit values (stored in lo and hi) | |
35 | |
36 ;Second Bank of Custom Functions: | |
37 ; The custom functions are stored in the internal EEPROM after 0x180 | |
38 ; any custom function occupies 4 byte: | |
39 ; 2 byte (low:high) store the default value, reset from menu "reset" | |
40 ; if bit16=1 then the custrom function is 15bit value, if not it's a 8bit value | |
41 ; 2 byte (low:high) store the actual value | |
42 ; defaults for custom functions are in menu "reset" | |
43 ; get values with GETCUSTOM8 .x with x=0...32 for 8 Bit values (stored in WREG) | |
44 ; or with GETCUSTOM15 .x with x=0...32 for 15 Bit values (stored in lo and hi) | |
45 | |
79 | 46 ; [jDG] 2010-11-30 More fancy displsy of the various CF types |
47 ; data types. When we do have a 8bit data (bit16=0), the high byte serves to | |
48 ; define the display format: | |

50 CF_INT8 EQU 0 ; Default display, 8 or 15 bits values. | |
