# Notes on device side clocks
The device side firmware uses a range of different clocks. Here is an attempt to document the clocks in use and for what they are used.
- [Notes on device side clocks](#notes-on-device-side-clocks)
- [Slow clock](#slow-clock)
- [Main Oscillator / MAINCK](#main-oscillator--mainck)
- [PLL clock](#pll-clock)
- [Master Clock MCK, Processor Clock PCK, USB clock UDPCK](#master-clock-mck-processor-clock-pck-usb-clock-udpck)
- [Peripheral clocks](#peripheral-clocks)
- [1 kHz RTC: TickCount functions](#1-khz-rtc-tickcount-functions)
- [Occasional PWM timer](#occasional-pwm-timer)
- [Occasional TC0+TC1 / CountUS functions](#occasional-tc0tc1--countus-functions)
- [Occasional TC0+TC1+TC2 SSP_CLK from FPGA / CountSspClk functions](#occasional-tc0tc1tc2-ssp_clk-from-fpga--countsspclk-functions)
- [Occasional TC0+TC1 / Ticks functions](#occasional-tc0tc1--ticks-functions)
## Slow clock
~32kHz internal RC clock
