Example 1: Consider that the transfer size is 512 bytes and the MaxPacketSize is
programmed as 64 bytes, the Buffer Length register need not be filled. This is
because the transfer size is a multiple of MaxPacketSize, and the MaxPacketSize
packets will be automatically validated because the last packet is also of
MaxPacketSize.
Example 2: Consider that the transfer size is 510 bytes and the MaxPacketSize is
programmed as 64 bytes, the Buffer Length register should be filled with 62 bytes just
before the MCU writes the last packet of 62 bytes. This ensures that the last packet,
which is a short packet of 62 bytes, is automatically validated.
Use bit VENDP in the Control register if you are not using the Buffer Length register.
This is applicable only to PIO mode access.
OUT endpoint:
The DATACOUNT value is automatically initialized to the number of
data bytes sent by the host on each ACK.
Remark:
When using a 16-bit microprocessor bus, the last byte of an odd-sized
packet is output as the lower byte (LSByte).
Remark:
Buffer Length is valid only after an interrupt is generated for the bulk
endpoint.
9.3.5
Buffer Status register (address: 1Eh)
This register is accessed using index. The endpoint index must first be set before
accessing this register for the corresponding endpoint. It reflects the status of the
double buffered endpoint FIFO. This register is valid only when the endpoint is
configured to be a double buffer.
Remark:
This register is not applicable to the control endpoint.
Table 39
shows the bit allocation of the Buffer Status register.
