Description
Transfer Type
Selects the transfer type for the pipe selected by the
PIPESEL bits (selected pipe)
• PIPE1 and PIPE2
00: Pipe not used
01: Bulk transfer
10: Setting prohibited
11: Isochronous transfer
• PIPE3 to PIPE5
00: Pipe not used
01: Bulk transfer
10: Setting prohibited
11: Setting prohibited
• PIPE6 and PIPE7
00: Pipe not used
01: Setting prohibited
10: Interrupt transfer
11: Setting prohibited
Before setting PID to BUF for the selected pipe
(before starting USB communication using the
selected pipe), be sure to set these bits to the value
other than 00.
Modify these bits while the PID bits for the selected
pipe are set to NAK. Before modifying these bits after
modifying the PID bits for the selected pipe from BUF
to NAK, check that CSSTS and PBUSY are 0.
However, if the PID bits have been modified to NAK
by this module, checking PBUSY through software is
not necessary.
