RO

RECEIVED_PID_STS (RECEIVED_PID_STS_0): The hardware updates 
this field with the received PID for transactions in either direction. When the 
controller is writing data, this field is updated with the handshake PID that is 
received from the device. When the host controller is reading data, this field 
is updated with the data packet PID (if the device sent data), or the 
handshake PID (if the device NAKs the request). This field is valid when the 
hardware clears the GO_DONE#_CNT bit. Reset Default = 0.

SEND_PID_CNT (SEND_PID_CNT_0): The hardware sends this PID to 
begin the data packet when sending data to USB (ie. WRITE_READ#_CNT is 
asserted). Software will typically set this field to either DATA0 or DATA1 PID 
values. Reset Default = 0

TOKEN_PID_CNT (TOKEN_PID_CNT_0): The hardware sends this PID as 
the Token PID for each USB transaction. Software will typically set this field 
to either IN, OUT or SETUP PID values. Reset Default = 0.
