the specific bit. Refer to Table 12-15 for a description of each interrupt source.
1 Interrupt Enabled
0 Interrupt Disabled
End of transfer interrupt. Set when the end of a transfer has been reached. An EOT
interrupt is generated when a packet with a size less than the maximum packet size or
the first zero-length packet following maximum size packets is sent or received. For OUT
endpoints, the EPDPn must be read before clearing this interrupt in order to determine
the number of bytes of remaining data in the FIFO for the last transfer. For OUT
endpoints, any packets received from the host cause a NAK response until the EOT
interrupt is cleared. For IN endpoints, the user must wait until the EOT interrupt is set
before writing the next transfer to the FIFO.
