LCD_VMODE[1:0]

2401[7:6]

00 00 R/W

Specifies how VLCD is generated. See

2.5.8.4

for the definition of V3P3L.

LCD_VMODE Description

11

External VLCD

10

LCD boost and LCD DAC enabled

01

LCD DAC enabled

00

No boost and no DAC. VLCD=V3P3L.

LCD_Y

2400[2]

0 – R/W

LCD Blink Frequency (ignored if blink is disabled).
1 = 1 Hz, 0 = 0.5 Hz

LKPADDR[6:0]

2887[6:0]

0 0 R/W The address for reading and writing the RTC lookup RAM

LKPAUTOI

2887[7]

0 0 R/W

Auto-increment flag. When set, LKPADDR auto-increments every time
LKP_RD or LKP_WR is pulsed. The incremented address can be read at
LKPADDR[6:0].

LKPDAT[7:0]

2888[7:0]

0 0 R/W The data for reading and writing the RTC lookup RAM.

LKP_RD
LKP_WR

R/W
R/W

Strobe bits for the RTC lookup RAM read and write. When set, the
LKPADDR[6:0] field and LKPDAT register is used in a read or write
operation. When a strobe is set, it stays set until the operation completes, at
which time the strobe is cleared and LKPADDR[6:0] is incremented if the
LKPAUTOI bit is set.

MPU_DIV[2:0]

2200[2:0]

0 0 R/W

MPU clock rate is:

MPU Rate = MCK Rate * 2

-(2+MPU_DIV[2:0])

.

The maximum value for MPU_DIV[2:0] is 4. Based on the default values of
the PLL_FAST bit and MPU_DIV[2:0], the power up MPU rate is 6.29 MHz / 4
= 1.5725 MHz. The minimum MPU clock rate is 38.4 kHz when PLL_FAS T =
1.

MUX0_SEL[3:0]

2105[3:0]

0 0 R/W Selects which ADC input is to be converted during time slot 0.

MUX1_SEL[3:0]

2105[7:4]

0 0 R/W Selects which ADC input is to be converted during time slot 1.

MUX2_SEL[3:0]

2104[3:0]

0 0 R/W Selects which ADC input is to be converted during time slot 2.

MUX3_SEL[3:0]

2104[7:4]

0 0 R/W Selects which ADC input is to be converted during time slot 3.

MUX4_SEL[3:0]

2103[3:0]

0 0 R/W Selects which ADC input is to be converted during time slot 4.

MUX5_SEL[3:0]

2103[7:4]

0 0 R/W Selects which ADC input is to be converted during time slot 5.

MUX6_SEL[3:0]

2102[3:0]

0 0 R/W Selects which ADC input is to be converted during time slot 6.

MUX7_SEL[3:0]

2102[7:4]

0 0 R/W Selects which ADC input is to be converted during time slot 7.

MUX8_SEL[3:0]

2101[3:0]

0 0 R/W Selects which ADC input is to be converted during time slot 8.

MUX9_SEL[3:0]

2101[7:4]

0 0 R/W Selects which ADC input is to be converted during time slot 9.

MUX10_SEL[3:0]

2100[3:0]

0 0 R/W Selects which ADC input is to be converted during time slot 10.
