Data Sheet
USBD_STATUS_REG0
Table 76
The USBD status register 0 provides the SW with status indication for RX and TX FIFOs
and provides handshake control for both FIFOs. This register is read-only.
USBD_STATUS_REG1
Table 77
The USBD status register 1 provides the SW with internal handshake indication for RX
and TX FIFOs. This register is read/write (writing ’1’ resets the bit).
Note: RX_XFR_ACK are reflected in the corresponding RX_BYTECNT registers.

Function
1: Indicates RX Transfer Acknowledge for USBD
0: idle/busy
1: Indicates TX Transfer Acknowledge for USBD FIFO
0: idle/busy
Function
1: Indicates RX Fifo Endpoint N (N=7..0) is empty
0: not empty
The reset value is ’0’, but after reset the value changes
immediately.
1: Indicates TX Fifo Endpoint N (N=7..0) is full
0: normal operation
