Parameter
Currents in the following circuits are not included; on-chip pull-up resistors, internal LCD voltage dividing resistors,
output port drive currents.
Data includes power consumption for subsystem clock oscillation.
When the system clock control register, SCMOD, is set to 1001B, main system clock oscillation stops and the
subsystem clock is used.
Every values in this table is measured when the power control register (PCON) is set to "0011B".
