can uart support irq?

[yaohuarun]

I run following code in m5stack fire board

from machine import UART
uart1 = UART(1, tx=1, rx=3)
uart1.init(115200, bits=8, parity=None, stop=1)
def UART_ISR(t):
uart1.irq(handler=UART_ISR)

bu report error message:
'UART' object has no attribut 'irq'.
does uiflow support irq?

[m5stack]

Just like the mpy official document said. "Availability: Wipy". maybe future we will support this function, so pls give us some time.
