AWRL6432 ES1.0

Details

By default, the slicer LDO TLOAD is enabled during startup for stability purposes. After the oscillator is enabled, the current loading should be disabled automatically to reduce power and extend reliability.

Since presently the loading is not turned OFF automatically, higher than expected current is observed (~8mA).

Workaround

It is recommended to disable the load bit explicitly by setting the following field to save unnecessary power burnout :

TOP_PRCM: CLK_CTRL_REG1_LDO_CLKTOP = 0x1

This has been fixed in ES2.0
