PID[1:0]
00
R/W • This module sets PID to STALL (11) on receiving
the STALL handshake when the host controller
function is selected.
To specify each response type, set these bits as
follows.
• To make a transition from NAK (00) to STALL,
set 10.
• To make a transition from BUF (01) to STALL,
set 11.
• To make a transition from STALL (11) to NAK,
set 10 and then 00.
• To make a transition from STALL to BUF, set 00
(NAK) and then 01 (BUF).
Notes: 1. Only 0 can be read and 1 can be written to.
2. Only 1 can be written to.
