Flash Programming and Emulation
l   2-wire JTAG programming and emulation interface

 

System clock (fSYS)
l  Built-in high frequency 32 MHz oscillator (fHRC)

n  can be selected and set by the programmer as: 32/16/8/4 MHz@2.0~5.5V

n  Frequency Error: Within ±1% @ -40 ~ 105℃ @ 2.0 ~ 5.5V

 

Built-in high-frequency crystal oscillator circuit:
l  Can be connected with external 2~16MHz oscillator
l  As the system clock source, fSYS has the programmer option to use one of the four frequency splits of external crystal / 1/2/4/8
l  The built-in system clock monitoring circuit. If you select a crystal oscillator as the system clock source and the crystal oscillator circuit stops, the system clock source automatically switches to the built-in HRC and stays in this state until reset next time

 

Built-in low-frequency 32 kHz oscillator (LRC):
l  used as the clock source for Base Timer and wake up STOP
l  used as the clock sourse for WDT
l   Frequency Error: After the register correction, within ±4% @ -20 ~ 85℃ @ 4.0 ~ 5.5V

 

Low-voltage Reset (LVR)
l   4 options of reset voltage: 4.3/3.7/ 2.9/1.9V
l  the default value can be selected by the Code Option

 

Interrupts (INT)
