.currentpll R/O Property


Returns current PLL mode of the device


Enum (no_yes, byte)

Value Range:

0- NO: PLL is off, the device runs at low speed with reduced power consumption.

1- YES: PLL is on, the device runs at maximum speed, x8 faster than low speed.

After the external reset the device typically boots with PLL on. You can switch PLL off and on programmatically by using the sys.newpll method and then "self-resetting" the device using the sys.reboot method.

Actual PLL mode change only takes place after you "self-reset" the device using sys.reboot method or the device self-resets due to some other reason (for instance, there is a self reset after a new BASIC application upload, or when you hit "restart" button in TIDE). External resets — power-up and RST pin reset (reset button reset) — set the PLL to default state (typically ON). On some devices there is a hardware jumper that defines the post-external reset state of the PLL.

Not all Tibbo devices have PLL — to find out if yours does, refer to its platform documentation (for example, EM1000's is here).
