Single-chip 16/32-bit microcontrollers
8.1 Power consumption measurements for LPC2109/01, LPC2119/01,
LPC2129/01 devices
The power consumption measurements represent typical values for the given conditions.
The peripherals were enabled through the PCONP register, but for these measurements,
the peripherals were not configured to run. Peripherals were disabled through the PCONP
register. Refer to the LPC2119/2129/2194/2292/2294 User Manual for a description of the
PCONP register.
