0
L
R/W
Configuration for DIO30/SEG50 through DIO28/SEG48. LCD_BITMAP[48] correspond-
ing to DIO28/SEG48 is only applicable to the 71M6534. Unused bits should be set to zero.
1 = LCD pin, 0 = DIO pin.

L
R/W
Configuration for DIO43/SEG63 through DIO41/SEG61 and DIO39/SEG59 through
DIO36/SEG56. LCD_BITMAP[62] corresponding to DIO42/SEG62 and
LCD_BITMAP[59:56] corresponding to DIO39/SEG59 through DIO36/SEG56 are only
applicable to the 71M6534. Unused bits should be set to zero.
1 = LCD pin, 0 = DIO pin.

R/W
Configuration for DIO51/SEG71 through DIO44/SEG64. LCD_BITMAP[66] correspond-
ing to DIO46/SEG66 is only applicable to the 71M6534. Unused bits should be set to zero.
1 = LCD pin, 0 = DIO pin.
LCD_BLKMAP18
[3:0]
205A[3:0]
0
L
R/W
Identifies which segments connected to SEG18 should blink. 1 means blink. The
most significant bit corresponds to COM3, the least significant bit to COM0.
LCD_CLK[1:0]
2021[1:0]
0
L
R/W
Sets the LCD clock frequency for the COM/SEG pins (not the frame rate) according to
the following (fw = 32768 Hz):
00 = fw/512, 01 = fw/256, 10 = fw/128, 11 = fw/64
LCD_DAC[2:0]
20AB[3:1]
0
L
R/W
LCD contrast control DAC. Adjusts the LCD voltage in steps of 0.2 V from V3P3SYS
(mission mode) or VBAT (brownout/LCD modes).
