nRF52832-QFAA : THE PIN "P0.10/NFC2" can not output a PWM wave

Hi,Nordic Tech Support friends:

       I try to use the pin "P0.10/NFC2" to ooutput a PWM wave,but only output  zero.

The schematic is as follows:

The PWM signal should appear on both sides of R07,but not appear any PWM signal ,only zero.

I try to move away the MOS-FET "HL20N04",The problem still cannot be solved.

I have  measured the connectivity between the chip and the resistor ,it's good.

I try to give a PULLUP signal to the resistor R07  from the MCU‘s pin “P0.10/NFC2” ,and about a  3V voltage appears on the  both sides of R07.

To sum up, the pin “P0.10/NFC2”  can give PULLUP signal,and can not give a PWM wave.

It was so strange,I am expecting your prompt reply.

Thanks!
