Output RX.
The received BUS signal will be output to the RX pin:
BUS < Vthr_cnt – 0.5 * Vthr_hys
→ RX = low
BUS > Vthr_cnt + 0.5 * Vthr_hys
→ RX = high
This output is a push-pull driver between VCC and GND with an output current of 1mA.

8.6 MODE Input EN
The AS8530 is switched from normal mode to the standby/sleep mode with a falling edge on EN and keeping TX high for TSTNDY_trigger time.
Device is switched from standby mode to normal mode with a rising edge at the EN pin. The mode change for AS8530 with a falling edge at EN
can be done independently from the state of the bus transceiver. Device enters into Serial port mode by forcing EN low and driving TX high to low
within Ttx_SP_trigger time after EN forced to low.
This ensures the direct control of device to enter into Standby/Sleep mode by microcontroller using EN pin.
Figure 11. EN Pin Functionality
The EN input has an internal active pull down to secure that if this pin is not connected, a low level will be generated.
