Section 23 USB 2.0 Host/Function Module (USB)
(3)
The isochronous interval can be set using the IITV bits in PIPEPERI. The interval counter enables
the functions shown in table 23.26 when the function controller function is selected. When the
host controller function is selected, this module generates the token issuance timing. When the
host controller function is selected, the interval counter operation is the same as the interrupt
transfer operation.
Table 23.26 Functions of the Interval Counter when the Function Controller Function is
The interval count is carried out when an SOF is received or for interpolated SOFs, so the
isochronism can be maintained even if an SOF is damaged. The frame interval that can be set is

This module initializes the interval counter under the following conditions.
1. Power-on reset
2. Software reset
3. USB bus reset
4. Buffer memory initialization using the ACLRM bit
