;First Bank of Custom Functions:
; The custom functions are stored in the internal EEPROM after 0x80
; any custom function occupies 4 byte:
; 2 byte (low:high) store the default value, reset from menu "reset"
; if bit16=1 then the custrom function is 15bit value, if not it's a 8bit value
; 2 byte (low:high) store the actual value
; defaults for custom functions are in menu "reset"
; get values with GETCUSTOM8	.x with x=0...32 for 8 Bit values (stored in WREG)
; or with GETCUSTOM15	.x with x=0...32 for 15 Bit values (stored in lo and hi)

;Second Bank of Custom Functions:
; The custom functions are stored in the internal EEPROM after 0x180
; any custom function occupies 4 byte:
; 2 byte (low:high) store the default value, reset from menu "reset"
