Note 1.
Current flowing through internal pull-up resistor. Current flowing when EEPROM is accessed is not
included.
2.
When
μ
PD75048 operates in high-speed mode with processor clock control register (PCC) set to 0011.
3.
When
μ
PD75048 operates in low-speed mode with PCC set to 0000.
4.
When the system clock control register (SCC) is set to 1001, the oscillation of the main system clock
is stopped, and the subsystem clock is used.
5.
When STOP instruction is executed with SCC set to 0000.
Note
Supply current when EEPROM is accessed is shown in EEPROM Characteristics.
