UART Module

Category

Functional

Function

UART RX interrupt erroneously set with 3x oversampling and MFCLK or BUSCLK as clock source

Description

When using BUSCLK or MFCLK for UART and 3x oversampling, the RXINT is getting set incorrectly. When using the UART module with BUSCLK or MFCLK as the source, and 3x oversampling mode, the RX interrupt may be set erroneously. Under these conditions TX data may also be corrupted.

Workaround

Use a higher oversampling rate when using BUSCLK or MFCLK. If 3x oversampling is required, utilize LFCLK.
