12.3.11 EP3 Data Register (EPDR3)
EPDR3 is a 64-byte transmit FIFO buffer for endpoint 3. EPDR3 stores one packet of transmit
data in the interrupt transfer for endpoint 3. If one packet of data is written and number of transmit
data is written in the packet enable register 3 (PKTE3), transmit data is valid. If one packet of data
is transmitted normally and the ACK handshake is returned from the host, the EP3TS bit in IFR0
is set. EPDR3 can be initialized by setting the EP3CLR bit in the FIFO clear register 0.
12.3.12 Data Status Register 0 (DASTS0)
DASTS0 indicates whether the IN FIFO data registers contain valid data or not. A bit in DASTS0
is set to 1 when data written to the corresponding IN FIFO becomes valid after the number of
transfer bytes is written in the packet enable register. A bit in DASTS0 is cleared to 0 when all
valid data is sent to the host. For endpoint 2, having a dual-FIFO configuration, the corresponding
bit in DASTS0 is cleared to 0 when both FIFOs become empty.
