Note:

1. * RTC OSC in slow mode for test condition.

2. set

²LCDEN²=1, set ²COM0EN²=1, reset ²RSEL²=0 in LCDC (1FH) register for ISTB5 measurement.

3. VBIAS voltage is design guarantee. Not for test.

4. VAVDD is the analog circuit supply voltage which does not have an external pin but is connected to VDD inside

the device.
