A prescaler factor of zero corresponds to “no clock.” The “no clock” condition is the UART power down
mode, in which the UART clock is turned off to reduce power consumption. Software must select the “no
clock” condition before entering a new baud rate. Otherwise, it could cause incorrect data to be received
or transmitted. The UnPSR register must contain a value other than zero when an external clock is used
at CKX.
