Notice:
ꢂ
The LVD function can improve the power on reset and brown-out reset performance. It will
increase about extra 100µA current consumption at 5V if LVD is enabled. The minimum working
voltage will be affect by the OSG option. It is very important to check this code option.
Turn on the OSG will improve the EMI performance. But the side effect is to increase the lowest
valid working voltage level.

If users select “32K X’tal” in “High_Clk” option, assembler will force “OSG” to be enabled.
If users select “RC” in “High_Clk” option, assembler will force “High_Clk / 2” to be enabled.
