1/5 bias for test only. In 1/4 bias LCD operation mode, VDD condition is 2.7 V to 6.0 V.
Data includes power consumption for subsystem clock oscillation.
For high-speed controller operation, the power control register (PCON) must be set to 0011B.
For low-speed controller operation, the power control register (PCON) must be set to 0000B.
When the system clock control register, SCMOD, is set to 1001B, main system clock oscillation stops and the
subsystem clock is used.
Currents in the following circuits are not included; on-chip pull-up resistors, output port drive currents, internal LCD voltage
dividing resistors, comparator.
