Notes 1.
The current flowing through the on-chip pull-up resistor, the current during EEPROM writing time, and
the current when the program threshold port (PTH) is operating are not included.
When the device is operated in the high-speed mode by setting the processor clock control register
(PCC) to 0011H.
When the device is operated in the low-speed mode by setting PCC to 0000H.
