EPi_Buf_Nmb
Buffer Start Number
The top block number of buffer
(1) EPi_TYP (Transfer Type) Bits (b15~b14)
These bits are used to set the transfer type of the endpoint.
(2) EPi_DIR (Transfer Direction) Bit (b13)
This bit is used to set the transfer direction of the endpoint.
After switching the transfer direction, clear the buffer by the BCLR bit.
(3) EPi_ITMD (Interrupt Toggle Mode) Bit (b12)
This bit sets the enable/disable of data resend function at interrupt transfer.
This bit can be set to “1” only when the transfer type is set to interrupt transfer (EPi_TYP bits = “10”). Set this
bit to “0” for other transfer modes.
When the data resend function is set to disable, the new data is transmitted at the next transmission by
toggling the DATA PID and the buffer, even if the ACK is not received after transmitting the data at interrupt
transfer. Here, the IVAL bit is cleared to “0” and the EPB_RDY bit is set to “1” (buffer ready interrupt has
occurred).
When the data resend function is set to enable, the normal toggle sequence is executed. When the
transmission completes normally, the DATA PID and the buffer got toggled to transmit the next data. In case
ACK cannot be received after the data is transmitted, the DATA PID and the buffer do not get toggle, and the
same data in the buffer is resent.
