9.6.5 USB Control register (USBCtrl - 0xFFE0 C228)
9.7.1 USB Command Code register (USBCmdCode - 0xFFE0 C210)
9.7 SIE command code registers
Table 324. USB Transmit Packet Length register (USBTxPLen - address 0xFFE0 C224) 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 325. USB Control register (USBCtrl - address 0xFFE0 C228) bit description
The SIE command code registers are used for communicating with the Serial Interface
Engine. See
information.
This register is used for sending the command and write data to the SIE. The commands
written here are propagated to the SIE and executed there. After executing the command,
the register is empty, and the CCEMPTY bit of USBDevIntSt register is set. See

-
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.
