26.3.36 PIPEn Control Registers (PIPEnCTR) (n = 1 to 9)
PIPEnCTR is a register that is used to confirm the buffer memory status for the corresponding
pipe, change and confirm the data PID sequence bit, determine whether auto response mode is set,
determine whether auto buffer clear mode is set, and set a response PID for PIPE1 to PIPE9. This
register can be set regardless of the pipe selection in PIPESEL.
This register is initialized by a power-on reset. PID[1:0] are initialized by a USB bus reset.
