1*4882a593Smuzhiyun* EFM32 timer hardware
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe efm32 Giant Gecko SoCs come with four 16 bit timers. Two counters can be
4*4882a593Smuzhiyunconnected to form a 32 bit counter. Each timer has three Compare/Capture
5*4882a593Smuzhiyunchannels and can be used as PWM or Quadrature Decoder. Available clock sources
6*4882a593Smuzhiyunare the cpu's HFPERCLK (with a 10-bit prescaler) or an external pin.
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunRequired properties:
9*4882a593Smuzhiyun- compatible : Should be "energymicro,efm32-timer"
10*4882a593Smuzhiyun- reg : Address and length of the register set
11*4882a593Smuzhiyun- clocks : Should contain a reference to the HFPERCLK
12*4882a593Smuzhiyun
13*4882a593SmuzhiyunOptional properties:
14*4882a593Smuzhiyun- interrupts : Reference to the timer interrupt
15*4882a593Smuzhiyun
16*4882a593SmuzhiyunExample:
17*4882a593Smuzhiyun
18*4882a593Smuzhiyuntimer@40010c00 {
