…terrupt driven API Low power mode for non-asynchronous API case is only available when RX is not used (RX pin is not defined). In that case TX starting function was using uarte_enable_locked() which tracks if UARTE is used by TX or RX and TXSTOPPED interrupt was disabling UARTE unconditionally. Because of that following attempt to TX start was assuming that UARTE is already enabled when it was disabled. Fixing it by using uarte_disable_locked function in TXSTOPPED handling. Code reordering was required to make uarte_disable_locked() available earlier. Upstream PR #: 81631 Signed-off-by: Krzysztof Chruściński <[email protected]>
