USBPD_Sink_CAPSENSE selecting a PPS voltage #2

Sorted out my previous problem by going to another machine, loading up the ModusToolbox and building and re-installing the USBPD_Sink_CAPSENSE app. This time it worked as advertised (i.e. no reboot every 4 seconds) on the same CY7113. After that I was able to play around with the EZ-PD Configurator 1.10 and turn off EPR and then it selected the highest fixed voltage which I was able to change between 20 and 15 Volts. Good. After that I tried to get PPS working and was not able to. Through the EZ-PD Configurator I was able to add a new PPS PDO and to disable the second (fixed) PDO. But try as I might, the CY7113 kept on outputting 5 Volts. So my question is how do I make the CY7113 use a PPS PDO as it seems to always request the highest fixed PDO voltage that it can negotiate? I don't mind whether the answer is in the EZ-PD Configurator (or some other configurator) or in the source code that Infineon/Cypress have helpfully provided (unlike many other vendors in this space). Note that the Apple 140 Watt power adapter doesn't do PPS so I used another adapter which does source PPS and works at 18 Volts selected with a different sink/trigger board.

Hi,

PMG1 doesn't support the PPS sink even though there is an option to configure it in the EZ-PD Configurator.
