Bit Bit Name
Initial
Value R/W Description
1, 0 PID[1:0] 00 R/W Even if the PID bits have been modified to NAK
after this module has issued S-SPLIT of the split
transaction for the selected pipe (while CSSTS
indicates 1), this module continues the transaction
until C-SPLIT completes. On completion of C-
SPLIT, this module sets PID to NAK.
(2) When the function controller function is selected
This module modifies the setting of these bits as
follows.
This module modifies PID to NAK on receiving
the setup packet. Here, this module sets VALID
to 1. PID cannot be modified until VALID is set
to 0.
This module sets PID to STALL (11) on
receiving the data of the size exceeding the
maximum packet size when PID has been set to
BUF.
This module sets PID to STALL (1x) on
detecting the control transfer sequence error.
This module sets PID to NAK on detecting the
USB bus reset.
This module does not reference to the setting of the
PID bits while the SET_ADDRESS request is
processed (auto processing).
Notes: 1. This bit is always read as 0. Only 1 can be written.
2. Only 1 can be written.
