9.10.3.5.1 Data transfer
9.10.3.5 USB Control register (USBCtrl - 0x4002 0028)
Table 165. USB Transmit Packet Length register (USBTxPLen - address 0x4002 0024) bit
This register controls the data transfer operation of the USB device. It selects the endpoint
buffer that is accessed by the USBRxData and USBTxData registers and enables reading
and writing them. USBCtrl is a read/write register.
Table 166. USB Control register (USBCtrl - address 0x4002 0028) bit description
When the software wants to read the data from an endpoint buffer it should make the
Read Enable bit high and should program the logical endpoint number. The control logic
will first fetch the packet length to the receive packet length register. Also the hardware
fills the receive data register with the first word of the packet.
The software can now start reading the receive data register. When the end of packet is
reached the Read Enable bit will be disabled by the control logic and RxENDPKT bit is set
in the Device interrupt status register.

The remaining number of bytes to be written to the
selected endpoint buffer. This field is decremented by 4 by
hardware after each write to USBTxData. When this field
decrements to 0, the TxENDPKT bit will be set in
USBDevIntSt.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
Description
Read mode control. Enables reading data from the OUT
endpoint buffer for the endpoint specified in the
LOG_ENDPOINT field using the USBRxData register.
This bit is cleared by hardware when the last word of
the current packet is read from USBRxData.
Read mode is disabled.
Read mode is enabled.
Write mode control. Enables writing data to the IN
endpoint buffer for the endpoint specified in the
LOG_ENDPOINT field using the USBTxData register.
This bit is cleared by hardware when the number of
bytes in USBTxLen have been sent.
Write mode is disabled.
Write mode is enabled.
