Figure 2 – Oscillator circuit

Where:

Rd is drive resistor, the value is 100Ω~ 300Ω.

C1 and C2 are load capacitors with same value, the range is ：10pF ~ 30pF.

XTAL is crystal oscillator, frequency is 2MHz ~ 6MHz.

Periphery modules

3.1 WDT/timer

[Description]

As shown in figure 3, in WDT/timer module, the 16-bit timer can also be used as the low 16-bit of 21-bit WDT.

The counting clock of WDT/timer can be directly provided by oscillator clock OscClk.
