When system control pin set to “H”, it should be connected to VDD1.
When system control pin set to “L”, it should be connected to VSS1.

Reserved for testing, must set with floating.
Connect OSC1 to VDD1.
This pin selects the supply voltage source of the digital circuit.
If system VDD1 is 3.0V ~ 3.3V, set DCPS=L to select Internal Regulator as digital circuit power.
If system VDD1 is 1.8V ~ 2.8V, set DCPS=H to select VDD1 as digital circuit power.
Select COM output sequence.
Fix CSEL=H to enable “Interlace” mode (recommended).
In interlace mode, COM2n (even number) is in the one side, COM(2n+1) (odd number) is in the
opposite side.
Short VD1I with VD1O externally by ITO or FPC.
VD1I is the power supply pin of the internal digital circuits.
When DCPS=L, VD1O is the output of the internal digital power regulator.
When DCPS=H, VD1O is provided by VDD1.
When writing EEPROM, VE should be pull-high externally.
When writing EEPROM, it needs external power supply voltage.
Reserve for testing only, recommend setting to [ MF2,MF1,MF0 = 0,0,0 ].
Reserve for testing only, recommend setting to [ DS1,DS0 = 0,0 ].
