What is the differnce between UART0, UART1, UART2 on kl25z ?
What is the operating voltage of RX/TX pin of kl25z ?
UART0 is a special UART module. It can support basic UART with DMA interface function, x4 to x32 oversampling of baud-rate.This module supports LIN slave operation.
The module can remain functional in VLPS mode provided the clock it is using remains enabled. It can support ISO7816.
UART1 and UART2 are basic universal asynchronous receiver/transmitter (UART) modules with DMA function support. Generally, these modules are used in RS-232, RS-485, and other communications. This module supports LIN Slave operation.
UART pins are digital. So the operation voltage depends on VDD voltage value.
Hope my reply can help you.
