For proper operation, do not modify VSUPPLY[1:0] while the LCDEN bit is asserted. VSUPPLY[1:0]
must also be configured according to the external hardware power supply configuration.

LCD Voltage Supply Register (LCDSUPPLY)
LCD Module Frame Frequency Interrupt Enable — Enables an LCD interrupt event that coincides with the
LCD module frame frequency.
0 No interrupt request is generated by this event.
1 The start of the LCD module frame causes an LCD module frame frequency interrupt request.
Full Complementary Drive Enable — This bit allows digital functionality that are shared with LCD pins to
operate as full complementary if the other conditions necessary have been met. The other conditions are:
VSUPPLY = 11 and RVEN = 0.
0 GPIO shared with LCD operate as open drain outputs, input levels and internal pullup resistors are referenced
1 If VSUPPLY = 11 and RVEN = 0, GPIO shared with LCD operate as full complementary outputs. Input levels
LCD Module Driver and Charge Pump Stop While in Wait Mode
0 Allows the LCD driver and charge pump to continue running during wait mode.
1 Disables the LCD driver and charge pump when MCU goes into wait mode.
LCD Module Driver and Charge Pump Stop While in Stop2 or Stop3 Mode
0 Allows LCD module driver and charge pump to continue running during stop2 or stop3.
1 Disables LCD module driver and charge pump when MCU goes into stop2 or stop3.
