Power-down mode
：
the value of random access memory RAM and special function register SFR is
saved, and all other functions are terminated. Most importantly, the microcontroller in power-down
mode can be awakened by various interrupts or resets.
Slow-frequency mode
：
users can slow down the system speed through the 8-bit system clock divider
to reduce power consumption.
Sub-frequency mode
：
the system clock applies the internal low-speed oscillator and the CPU runs
at a particularly slow speed.
。
Real-time clock (RTC) mode
：支
it supports the real-time clock function in all modes.
Watch mode
：
in power-down mode or idle mode, WDT overflow is used as an automatic timer to
wake up the CPU.
Monitor mode
：
detect the voltage in power-down mode, and reset when the voltage is particularly
low.
The CMT2380F17 is equipped with a Megawin proprietary On-Chip Debug (OCD) interface for In-Circuit
Emulator (ICE). The OCD interface provides on-chip and in-system non-intrusive debugging without any
target resource occupied. Several operations necessary for an ICE are supported, such as Reset, Run, Stop,
Step, Run to Cursor and Breakpoint Setting.
