39.4.12 Error Interrupt Enable Register (USBx_ERREN)
The Error Interrupt Enable Register contains enable bits for each of the error interrupt
sources within the USB Module. Setting any of these bits enables the respective interrupt
source in the ERRSTAT register. Each bit is set as soon as the error conditions is
detected. Therefore, the interrupt does not typically correspond with the end of a token
being processed. This register contains the value of 0x00 after a reset.
Addresses: USB0_ERREN is FFFF_9000h base + 8Ch offset = FFFF_908Ch
