A.2.1
This section describes the current consumption characteristics of the device as well as the conditions for
the measurements.
A.2.1.1
Run current is measured on VDDR pin. It does not include the current to drive external loads. Unless
otherwise noted the currents are measured in special single chip mode and the CPU code is executed from
RAM. For Run and Wait current measurements PLL is on and the reference clock is the IRC1M trimmed
to 1MHz. The bus frequency is 25MHz and the CPU frequency is 50MHz. Table A-8., Table A-9. and
Table A-10. show the configuration of the CPMU module and the peripherals for Run, Wait and Stop
current measurement.
