hi all,

i am looking at the reference manual for the LPC11U37 and has some queries on the USB peripheral register (EPSKIP).

Basically, writing to corresponding bits in this register will instruct the hardware to deactivate the corresponding endpoints....

But , in the document i was referring to (UM10462, rev 5.3, page 228, section 11.6.6), it states that bits 31:30 are reserved and writing to bits 29:0 will do the mentioned above...

My question is: how do these 30 bits (29:0) map to the 10 physical endpoints on the MCU?

Or is there a typo such that the correct bits should be 9:0 instead?

Thank you.

Hello,

I too am curious about this. I am working with the LPC15xx and the user manual (UM10736) also describes bits 29:0 as valid bits. Does anyone know how the 30 bits in the EPSKIP register map to the physical endpoints?

Thanks,
