Description
Specifies how VLCD is generated. See
LCD Blink Frequency (ignored if blink is disabled).
1 = 1 Hz, 0 = 0.5 Hz
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].
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 clock rate is:
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.
