UART maximum allowed deviation.

Question

hello everyone, i am looking for the maximum allowed deviation of the uart. The nRF52832 is clocked with 32 Mhz and has a baud rate of 19200. What is the maximum deviation for the counterpart? 
 
 thanks and reagards

HI Michael, 
 the UART on the nRF52832 uses the 16MHz clock (PCLK16M). 
 I could not find any specific number in our internal documentation, however, I think that in general that the nRF52832 should be able to handle up to 3% deviation. 
 This page covers some of the calculations for determining the maximum allowed deviation.
