up/pull-down resistors.

Regarding the values for subsystem clock operation, the TYP. and MAX. values do not include the peripheral

operating current. However, in HALT mode, the current flowing into the RTC is included.

Regarding the values in STOP mode, the TYP. and MAX. values do not include the peripheral operating

current.

Note 2.

When the HALT instruction is executed from the flash memory.

Note 3.

The listed currents do not include the current flowing into real-time clock 2, the clock output/buzzer output

controller, 12-bit interval timer, and watchdog timer.

Note 4.

When the high-speed system clock and subsystem clock are stopped.

Note 5.

When the high-speed on-chip oscillator and subsystem clock are stopped.

Note 6.

16-pin, 20-pin, 24-pin, and 32-pin products only.

Note 7.

When the high-speed on-chip oscillator and high-speed system clock are stopped. When AMPHS1 = 1 (ultra-

low power consumption oscillation). However, not including the current flowing into real-time clock 2, the 12-

bit interval timer, watchdog timer, and capacitive touch sensing unit.

Note 8.

When the high-speed on-chip oscillator and high-speed system clock are stopped. When RTCLPC = 1 and

AMPHS1 = 1 (ultra-low power consumption oscillation).

Note 9.

Regarding the value for current to operate the subsystem clock in STOP mode, refer to that in HALT mode.

Remark 1.

fIH: High-speed on-chip oscillator clock frequency

Remark 2.

fMX: High-speed system clock frequency (X1 clock oscillation frequency or external main system clock

frequency)

Remark 3.

Except for subsystem clock operation, the temperature condition of the TYP. value is TA = 25°C.

Remark 4.

fSUB: Subsystem clock frequency (XT1 clock oscillation frequency)
