AY0438
;The DP are not connected, but can be connected to seg8, 16, 24 & 32.
;For each digit, the segments are connected as:
; Seg A --> seg(8*n + 1)
; Seg B --> seg(8*n + 2)
; Seg C --> seg(8*n + 3)
; Seg D --> seg(8*n + 4)
; Seg E --> seg(8*n + 5)
; Seg F --> seg(8*n + 6)
; Seg G --> seg(8*n + 7)
;where n = 0, 1, 2 and 3 for MSD, 3rdSD, 2ndSD and LSD respectively.
;The firmware uses the values in registers:
; MSD, THRDSD, SCNDSD and LSD to determine the values to be
;pulsed to the AY0438.
;In this example, a pushbutton connected to PORTB bit 7
;is checked periodically to see if it has been pressed. If so,
;the LCD values in locations MSD to LSD are updated.
