Value R/W Description
8 CNTMD 0 R/W Continuous Transfer Mode
Specifies whether to use the selected pipe in
continuous transfer mode.
0: Non-continuous transfer mode
1: Continuous transfer mode
This bit is valid when PIPE1 to PIPE5 are selected
by the PIPESEL bits and bulk transfer is selected
(TYPE = 01).
Modify these bits while CSSTS is 0 and PID is NAK
and before the pipe is selected by the CURPIPE bits.
To modify these bits after completing USB
communication using the selected pipe, write 1 and
then 0 to ACLRM continuously to clear the FIFO
buffer assigned to the selected pipe while the
CSSTS, PID, and CURPIPE bits are in the above-
described state.
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 is not necessary.
