This tests that the RXIDLE callback is called correctly after a second lot
of bytes are received.

On stm32, the hardware generates an RXIDLE IRQ after enabling the UART,
because the RX line is technically idle.

These all require hardware connections, so live in a different directory.
Except for the IRQ_BREAK test of ESP32 devices a single UART with loopback
is sufficient.
General:
SAMD21: Due to the limited flash size only SAMD21 devices with external
flash support uart.irq().
IRQ_BREAK:
ESP32 needs different UART devices for creating and sensing a break.
Lacking a second UART the test is skipped for ESP32S2 and ESP32C3. RP2
does not pass the test reliable at 115200 baud, reason to be found.
Thus the upper limit is set to 57600 Baud.
Coverage:
esp32 pass when different UART devices are used.
rp2 pass up to 57600 baud
IRQ_RX:
SAMD21: Being a slow device it needs data to be sent byte-by-byte at
9600 baud, since the IRQ callback is scheduled delayed and then the
flags do not match any more. The data matches since it is queued in
the FIFO resp. ringbuffer.
CC3200: The test cannot be performed since no calls are accepted in the
IRQ handler like u.read(). Skipped.
Coverage:
cc3200 fail due to major differences in the implementation.
esp32 pass
nrf pass
renesas-ra pass
samd pass see the notes.
stm32 pass
IRQ_RXIDLE:
STM32: With PyBoard the IRQ is called several times, but only once with
the flag IRQ_RXIDLE set.
Coverage:
esp32 pass
mimxrt pass
renesas-ra pass
rp2 pass
samd pass for both SAMD21 and SAMD51
stm32 fail. see notes.
