Bit Name

Value R/W Description
15 to 0 TRNCNT[15:0] H'0000 R/W
When read:
Indicates the specified number of transactions if
TRENB = 0.
Indicates the current value of the transaction
counter if TRENB = 1.
Note: For the pipe in the transmitting direction, set
these bits to 0.
When the transaction counter is not used, set
these bits to 0.
To modify the value of these bits, set TRCLR to
1 before setting TRENB to 1.
Note: ∗ Modify these bits while CSSTS = 0, PID = NAK, and TRENB = 0.
Before modifying these bits after modifying the PID bits for the corresponding pipe from
BUF to NAK, make sure that CSSTS = 0 and PBUSY = 0. However, if the PID bits have
been modified to NAK by this module, checking of PBUSY is not necessary.
24.3.44 Device Address Configuration Registers (DEVADDn) (n = 0 to 9, A)
When the host controller function is selected, the DEVADDn registers specify the address and
port number of the hub to which the communication target function device is connected and also
specifies the communication speed of the function device.
These registers are initialized by a power-on reset.
