768-byte of extended RAM (XRAM)
-
Extended RAM (XRAM) supporting page access

On-chip debug interface (OCD)

Multiple power control modes: power-down mode, idle
mode, slow-frequency mode, sub-frequency mode,
RTC mode, watch mode, and monitor mode
-
All interrupts supporting to wake up the CPU
from IDLE mode
-
10 interrupt sources supporting to wake up the
CPU in power-down mode
-
Slow-frequency mode and sub-frequency mode
supporting low-speed MCU operation
-
RTC mode supporting real-time clock (RTC) to
wake up the CPU in power-down mode
-
Watch mode supporting watchdog (WDT) to
wake up the CPU in power-down mode
-
Monitor mode supporting BOD1 to wake up the
CPU in power-down mode

Operating frequency range: up to 25 MHz
-
External crystal oscillator mode, 0–12 MHz at
2.0–3.6 V and 0–25 MHz at 2.4–3.6 V
-
CPU operating frequency can reach 12 MHz at
1.8-3.6 V and 25 MHz at 2.2-3.6 V
-
When on-chip clock frequency multiplier (CKM)
is at 2.7–3.6 V, the CPU operating frequency
can reach 36 MHz.

Double data pointer

Interrupt control
-
16 interrupt sources, 4 priority levels
-
3 external interrupts nINT0/1/2, with filtering
-
All external interrupts supporting high/low or
rising/falling edge triggering
