The PID bits in DCPCTR and PIPEnCTR are used to set the response PID for each pipe.
The following shows this module operation with various response PID settings:
• Response PID settings when the host controller function is selected:
Setup transactions for the DCP are set with the SUREQ bit.
• Response PID settings when the function controller function is selected:
For setup transactions, an ACK response is always returned, regardless of the PID setting, and the
USB request is stored in the register.
This module may carry out writing to the PID bits, depending on the results of the transaction.
• When the host controller function has been selected and the response PID is set by hardware:
The response PID is used to specify the execution of transactions.
A. NAK setting: Using pipes is disabled. No transaction is executed.
B. BUF setting: Transactions are executed based on the status of the buffer memory.
C. STALL setting: Using pipes is disabled. No transaction is executed.
The response PID is used to specify the response to transactions from the host.
A. NAK setting: The NAK response is always returned in response to the generated
B. BUF setting: Responses are made to transactions based on the status of the buffer memory.
C. STALL setting: The STALL response is always returned in response to the generated
