bit 31-24
VPLEN<7:0>: V
BUS pulsing charge length bits
Sets the duration of the VBUS pulsing charge in units of 546.1 µs. (The default setting corresponds to 32.77
ms.)
bit 23-20
WTCON<3:0>: Connect/Disconnect filter control bits
Sets the wait to be applied to allow for the connect/disconnect filter in units of 533.3 ns. The default setting
corresponds to 2.667 µs.
bit 19-6
WTID<3:0>: ID delay valid control bits
Sets the delay to be applied from IDPULLUP being asserted to IDDIG being considered valid in units of
4.369ms. The default setting corresponds to 52.43ms.
bit 15-12
DMACHANS<3:0>: DMA Channels bits
These read-only bits provide the number of DMA channels in the USB module. For the PIC32MZ EF family,
this number is 8.
bit 11-8
RAMBITS<3:0>: RAM address bus width bits
These read-only bits provide the width of the RAM address bus. For the PIC32MZ EF family, this number
is 12.
bit 7-4
RXENDPTS<3:0>: Included RX Endpoints bits
This read-only register gives the number of RX endpoints in the design. For the PIC32MZ EF family, this
number is 7.
bit 3-0
TXENDPTS<3:0>: Included TX Endpoints bits
These read-only bits provide the number of TX endpoints in the design. For the PIC32MZ EF family, this
number is 7.
