3.4 PLL0.1: PLL0 (Main PLL) remains enabled and connected in Deep
Sleep and Power-down modes
Introduction:
If the main PLL (PLL0) is enabled and connected before entering Deep Sleep or
Power-down modes, main PLL (PLL0) automatically turns off and disconnects after the
chip enters Deep Sleep mode or Power-down mode leading to reduced power
consumption.
Problem:
If the main PLL (PLL0) is enabled and connected before entering Deep Sleep or
Power-down modes, it will remain enabled and connected after the chip enters Deep
Sleep mode or Power-down mode causing the power consumption to be higher.
Work-around:
In the software, user must disable and disconnect the main PLL (PLL0) before entering
Deep Sleep and Power-down modes to reduce the power consumption. This must be
done only if the main PLL (PLL0) was enabled and connected before entering Deep Sleep
mode or Power-down mode.
The code below demonstrates the steps to disable and disconnect the main PLL0:
PLL0CON &= ~(1<<1);
PLL0FEED = 0xAA;
PLL0FEED = 0x55;
while ((PLL0STAT & (1<<25)) != 0x00); /* Wait for main PLL (PLL0) to disconnect */
PLL0CON &= ~(1<<0);
PLL0FEED = 0xAA;
PLL0FEED = 0x55;
while ((PLL0STAT & (1<<24)) != 0x00); /* Wait for main PLL (PLL0) to shut down */
/************** Then enter into Deep sleep mode or Power-down mode*****************/
