10.5.5
DcBufferStatus register (R/W: 021Eh)
This register is accessed using an index. The endpoint index must first be set before
accessing this register for the corresponding endpoint. It reflects the status of the endpoint
FIFO.
Table 112
shows the bit allocation of the DcBufferStatus register.
[1]
The reserved bits should always be written with the reset value.
10.5.6
Endpoint MaxPacketSize register (R/W: 0204h)
This register determines the maximum packet size for all endpoints, except control 0. The
register contains 2 B, and the bit allocation is given in
Table 114
.
Each time the register is written, the Buffer Length registers of all endpoints are
reinitialized to the FFOSZ field value. The NTRANS bits control the number of
transactions allowed in a single microframe (for high-speed isochronous and interrupt
endpoints only).
