Description
MISC. PINS
Auxiliary VDD. This pin is connected to the main VDD bus within the IC. It’s
provided to facilitate chip configurations in COG application.
There’s no need to connect VDDX to main VDD externally and it should NOT
be used to provide VDD power to the chip.
Test control. There’s an on-chip pull-up resistor for TST4. Leave it open
during normal use.
Test I/O pins. Leave these pins open during normal use.
Dummy pins are NOT connected inside the IC.
Note: Several control registers will specify “0 based index” for COM and SEG electrodes. In those
situations, COMX or SEGX will correspond to index X-1, and the value range for those index register will be
0~63 for COM and 0~131 for SEG.

This command is used for set cursor update mode function. When cursor update mode sets, UC1701x will
update register CR with the value of register CA. The column address CA will increment with write RAM
data operation but the address wraps around will be suspended no matter what WA setting is. However, the
column address will not increment in read RAM data operation. The set cursor update mode can be used to
implement “write after read RAM” function. The column address (CA) will be restored to the value, which is
before the set cursor update mode command, when reset cursor update mode.
The purpose of this pair commands and their feature is to support “write after read” function for cursor
implementation.
19. Reset Cursor Update Mode
