Bit6(read/write)(PLL enable signal)
0/1=DISABLE/ENABLE
The relation between 32.768K and 3.679M can see Fig7.
Fig7. The relation between 32.768K and 3.679K .
Bit7 IDLE: sleep mode selection bit
0/1=sleep mode/IDLE mode. This bit will decide SLEP instruction which mode to go.
These IDLE mode can be waken up by TCC clock or Watch Dog or PORT9 and run from “SLEP” next
instruction.
These SLEEP mode can be waken up by Watch Dog or PORT9 and run from address “00”.

Bit4(Read Only)(Low battery signal)
If the battery voltage is under 3.6V then sends a ‘0’ signal to RA register bit4 or a ‘1’ signal to this Bit if VDD
is over 3.8V.
Bit5(read/Write)(Low battery detect enable)
0/1 = low battery detect DISABLE/ENABLE.
The relation between /LPD,/POVD and /LOW_BAT can see Fig6.
0/1 = Battery voltage is low/Normal .
