R/W
LCD Blink Frequency (ignored if blink is disabled).
1 = 1 Hz, 0 = 0.5 Hz
0 0 R/W The address for reading and writing the RTC lookup RAM
Auto-increment flag. When set, LKPADDR auto-increments every time
0 0 R/W LKP_RD or LKP_WR is pulsed. The incremented address can be read at
LKPADDR[6:0].
0 0 R/W The data for reading and writing the RTC lookup RAM.
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
0 0 R/W operation. When a strobe is set, it stays set until the operation completes, at
0 0 R/W which time the strobe is cleared and LKPADDR[6:0] is incremented if the
LKPAUTOI bit is set.
MPU clock rate is:
MPU Rate = MCK Rate * 2-(2+MPU_DIV[2:0]).
0 0 R/W 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.
0 0 R/W Selects which ADC input is to be converted during time slot 0.
0 0 R/W Selects which ADC input is to be converted during time slot 1.
0 0 R/W Selects which ADC input is to be converted during time slot 2.
0 0 R/W Selects which ADC input is to be converted during time slot 3.
0 0 R/W Selects which ADC input is to be converted during time slot 4.
0 0 R/W Selects which ADC input is to be converted during time slot 5.
0 0 R/W Selects which ADC input is to be converted during time slot 6.
0 0 R/W Selects which ADC input is to be converted during time slot 7.
0 0 R/W Selects which ADC input is to be converted during time slot 8.
0 0 R/W Selects which ADC input is to be converted during time slot 9.
0 0 R/W Selects which ADC input is to be converted during time slot 10.
