NOTES:

1. Data includes power consumption for subsystem clock oscillation.

2. When the system clock control register, SCMOD, is set to 1001B, main system clock oscillation stops and the

subsystem clock is used.

3. Currents in the following circuits are not included; on-chip pull-up resistors, internal LCD voltage dividing resistors,

output port drive currents.
