UART CONFIG in nrf51 reference manualhttps://devzone.nordicsemi.com/f/nordic-q-a/1736/uart-config-in-nrf51-reference-manualSection 28.9.9 of the nrf51 reference manual shows the Config register has 3 defined bits, BBA. A is for Hardware Flow Control and is one bit, 0 or 1, which makes sense. However the description for parity, which has the two BB bits, has exclude parityen-USTelligent Community 13Tue, 04 Mar 2014 13:50:23 GMTRE: UART CONFIG in nrf51 reference manualhttps://devzone.nordicsemi.com/thread/7621?ContentTypeID=1Tue, 04 Mar 2014 13:50:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4e682f0a-f76b-48f6-8516-13ef68c07316Ole Morten<p>There is a PAN #40 on reading the CONFIG register, basically saying that reading this register will always give bogus data. This is the reason for the apparently wrong reset value for this register, and should hence should not have any consequences.</p> <p>However, the reset value for the BAUDRATE register seems to be a bug in the Reference Manual, as the real reset value is 0x04000000 (i.e. 250000 baud). I&#39;ve reported this internally, so thanks for letting us know!</p><div style="clear:both;"></div>
