idle mode with lpc9102

Zoran Tosic

Hello all,

I'm playing with lpc900_idle.zip example measuring current in idle mode with lpc9102. It's the same as in normal mode ~6mA.

I'm getting the same result even when PCON is set to 0x03 (total power down).

Strange. Any idea what could be wrong?

Thank you in advance!

    Maybe something is waking the device up? You can toggle an led to indicate IDLE mode state and then watch the led to be sure the device is in IDLE mode. For example:

    .
.
.
while (1)
  {
  led_off();
  //enable IDLE mode (set PCON)
  led_on();
  }
.
.
.

    If the led stays off, then you know the device is in IDLE mode.
