PIC18F46J50 FAMILY
21.2.4
Each of the 16 possible bidirectional endpoints has its
own independent control register, UEPn (where ‘n’
represents the endpoint number). Each register has an
identical complement of control bits.
Register 21-4 provides the prototype.
The EPHSHK bit (UEPn<4>) controls handshaking for
the endpoint; setting this bit enables USB handshaking.
Typically, this bit is always set except when using
isochronous endpoints.
The EPCONDIS bit (UEPn<3>) is used to enable or
disable USB control operations (SETUP) through the
endpoint. Clearing this bit enables SETUP transac-
tions. Note that the corresponding EPINEN and
EPOUTEN bits must be set to enable IN and OUT

EPHSHK: Endpoint Handshake Enable bit
1 = Endpoint handshake enabled
0 = Endpoint handshake disabled (typically used for isochronous endpoints)
EPCONDIS: Bidirectional Endpoint Control bit
If EPOUTEN = 1 and EPINEN = 1:
1 = Disable Endpoint n from control transfers; only IN and OUT transfers allowed
0 = Enable Endpoint n for control (SETUP) transfers; IN and OUT transfers also allowed
EPOUTEN: Endpoint Output Enable bit
1 = Endpoint n output enabled
0 = Endpoint n output disabled
EPINEN: Endpoint Input Enable bit
1 = Endpoint n input enabled
0 = Endpoint n input disabled
EPSTALL: Endpoint Stall Indicator bit
1 = Endpoint n has issued one or more STALL packets
0 = Endpoint n has not issued any STALL packets

transactions. For Endpoint 0, this bit should always be
cleared
Endpoint 0 as the default control endpoint.
The EPOUTEN bit (UEPn<2>) is used to enable or
disable USB OUT transactions from the host. Setting
this bit enables OUT transactions. Similarly, the
EPINEN bit (UEPn<1>) enables or disables USB IN
transactions from the host.
The EPSTALL bit (UEPn<0>) is used to indicate a
STALL condition for the endpoint. If a STALL is issued
on a particular endpoint, the EPSTALL bit for that end-
point pair will be set by the SIE. This bit remains set
until it is cleared through firmware, or until the SIE is
reset.
