Slicer LDO Test LOAD (TLOAD) not disabled after startup
IWRL6432 ES1.0
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).
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
