https://devzone.nordicsemi.com/f/nordic-q-a/10870/nrf51-dk-timersHi, File &quot;nrf_drv_config.h&quot; defines both TIMER1_CONFIG_BIT_WIDTH and TIMER2_CONFIG_BIT_WIDTH as &quot;TIMER_BITMODE_BITMODE_16Bit&quot;, can these timers be configured as 24 bit / 32 bit timers as well? I am asking because after changing TIMER1_CONFIG_BIT_WIDTHen-USTelligent Community 13Tue, 15 Dec 2015 09:41:08 GMThttps://devzone.nordicsemi.com/thread/40667?ContentTypeID=1Tue, 15 Dec 2015 09:41:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:25979bca-90df-423f-b401-112999c5ccdcOle Bauck<p>The documentation can be somewhat confusing because it is split up into a Reference Manual and a Product Specification. The Product Specification will tell you what is actually available on the specific chip. On nRF51x22, TIMER1 and TIMER2 have only bitwidth 8/16, while TIMER0 has bitwidth 8/16/24/32. All timers have 4 compare registers. This information is in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.pdf.ps/nRF51822_PS_v3.1.pdf">Product Specification</a> part 4.2.</p> <p>You can decide if you want to use the driver nrf_drv_timer or if you want to manipulate the registers dircetly (like in the github example), this is a matter of taste. I will advise you to not do both (at the same time) if you dont absolutely know what you are doing.</p><div style="clear:both;"></div>
