LPCOpen - Power Management issue

Dear members,

I'm using the LPC1112 in my project.

According the LPCOpen documentation, the LPC1112 device is supported by the definition CHIP_LPC11CXX
http://www.lpcware.com/content/project/lpcopen-platform-nxp-lpc-microcontrollers/lpcopen-v2xx-online...

Also according the datasheet, LPC1112 and LPC11Cxx supports three sleep modes (sleep, deep-sleep and deep power down)

However, looking into the LPCOpen implementation for the power management (pmu_11xx.c), there are some defines that disable the deep sleep for the definition CHIP_LPC11CXX. Just the deep power mode is available.

The question: Is there a reason for this? Has the chip a bug for deep sleep? I tried to put the chip in deep sleep mode using registers, but without success.

Thank you,

Claudio Kunde

I managed to put the chip in Deep Sleep and Deep Power Mode developing my driver.

The LPCOpen, for power management, is poor and have problems yet. I disadvise the developers to use the methods in pmu_11xx.h

The better way is read the User Manual and develop the driver.
