23.4.8
This module has the following functions pertaining to isochronous transfers.
1. Notification of isochronous transfer error information
2. Interval counter (specified by the IITV bit)
3. Isochronous IN transfer data setup control (IDLY function)
4. Isochronous IN transfer buffer flush function (specified by the IFIS bit)
This module does not support the High Bandwidth transfers of isochronous transfers.
Note: When using isochronous OUT transfer, see section 23.5.1, Note on Using Isochronous
(1)
This module has a function for detecting the error information noted below, so that when errors
occur in isochronous transfers, software can control them. Tables 23.24 and 23.25 show the
priority in which errors are confirmed and the interrupts that are generated.
1. PID errors
2. CRC errors and bit stuffing errors
3. Maximum packet size exceeded
4. Overrun and underrun errors
⎯ If the PID of the packet being received is illegal
⎯ If an error occurs in the CRC of the packet being received, or the bit stuffing is illegal
⎯ The maximum packet size exceeded the set value.
⎯ When host controller function is selected:
⎯ When function controller function is selected:
