Universal Serial Bus Module (USB)
ISTALL0 — Endpoint 0 Force STALL Bit for IN token
This read/write bit causes endpoint 0 to return a STALL handshake
when polled by an IN token by the USB host controller. The USB
hardware clears this bit when a SETUP token is received. Reset
clears this bit.
1 = Send STALL handshake
0 = Default
PULLEN — Pull-up Enable
This read/write bit controls the pull-up option for the USB D– pin if the
USB module is enabled.
1 = Configure D– pin to have internal pull-up
0 = Disconnect D– pin internal pull-up
ENABLE2 — Endpoint 2 Enable
This read/write bit enables endpoint 2 and allows the USB to respond
to IN or OUT packets addressed to endpoint 2. Reset clears this bit.
1 = Endpoint 2 is enabled and can respond to an IN or OUT token
0 = Endpoint 2 is disabled
ENABLE1 — Endpoint 1 Enable
This read/write bit enables endpoint 1 and allows the USB to respond
to IN packets addressed to endpoint 1. Reset clears this bit.
1 = Endpoint 1 is enabled and can respond to an IN token
0 = Endpoint 1 is disabled
