R/W
Identifies which segments connected to SEG18 and SEG19 should
blink. 1 means ‘blink.’ Most significant bit corresponds to COM3.
Least significant, to COM0.
LCD_CLK[1:0]

R/W
Sets the LCD clock frequency (for COM/SEG pins, not frame rate).

R/W
Enables the LCD display. When disabled, VLC2, VLC1, and VLC0
are ground as are the COM and SEG outputs.
LCD_MODE[2:0]
2021[4:2]

R/W
The LCD bias mode.
000: 4 states, 1/3 bias
001: 3 states, 1/3 bias
010: 2 states, bias
011: 3 states, bias
100: static display
LCD_NUM[4:0]
2020[4:0]
0
--
R/W
Number of dual-purpose LCD/DIO pins to be configured as LCD.
This will be a number between 0 and 18. The first dual-purpose pin
to be allocated as LCD is SEG41/DIO21. Thus if LCD_NUM=2,
SEG41 and SEG 40 will be configured as LCD. The remaining
SEG39 to SEG24 will be configured as DIO19 to DIO4.
DIO1 and DIO2 (plus DIO3 on the QFN-68 package) are always
available, if not used for the optical port.
See tables in Application Section.
LCD_ONLY
20A9[5]
0
W
Takes the 6521FE/DE to LCD mode. Ignored if system power is
present. The part will awaken when autowake timer times out, when
push button is pushed, or when system power returns.

R/W
LCD Segment Data. Each word contains information for from 1 to 4
time divisions of each segment. In each word, bit 0 corresponds to
COM0, on up to bit 3 for COM3.
These bits are preserved in LCD and SLEEP modes,
even if their pin is not configured as SEG. In this case,
they can be useful as general-purpose non-volatile
storage.

R/W
LCD Blink Frequency (ignored if blink is disabled or if segment is
off).
0: 1Hz (500ms ON, 500ms OFF)
1: 0.5Hz (1s ON, 1s OFF)
MPU_DIV[2:0]
2004[2:0]
0
R/W
The MPU clock divider (from 4.9152MHz). These bits may be pro-
grammed by the MPU without risk of losing control.
000-4.9152MHz, 001-4.9152MHz /2
1, …, 111-4.9152MHz /27
MPU_DIV remains unchanged when the part enters BROWNOUT
mode.
MUX_ALT
2005[2]
0
R/W
The MPU asserts this bit when it wishes the MUX to perform ADC
conversions on an alternate set of inputs.
