(d)
With this module, all of the received data packets are discarded if the ACLRM bit in PIPEnCTR is
set to 1. If a normal data packet has been received, the ACK response is returned to the host
controller. This function can be set only in the buffer memory reading direction.
Also, if the ACLRM bit is set to 1 and then to 0, the buffer memory of the pipe can be cleared
regardless of the access direction.
An access cycle of at least 100 ns is required between ACLRM = 1 and ACLRM = 0.
(e)
Either a single or double buffer can be selected for PIPE1 to PIPE5, using the DBLB bit in
PIPEnCFG. The double buffer is a function that assigns two memory areas specified with the
BUFSIZE bit in PIPEBUF to the same pipe. Figure 23.10 shows an example of buffer memory
settings for this module.
