block size of 64 bytes. The HCD may put a PTD with payload size of up to 64 bytes but not
more. Depending on the ATL or INTL buffer size, up to 32 ATL blocks and 32 INTL blocks
can be allocated. Note that a portion of the ATL or INTL buffer remains unused. This is
allowed but can be avoided by choosing the appropriate ATL or INTL buffer size and block
size.
The ISTL0 or ISTL1 buffer memory (for isochronous transfer) uses a different memory
management scheme (see
memory. While the PTD header remains 8 bytes for all PTDs, the PTD payload can be of
any size. The PTD payload, however, is padded to the next double word boundary when
the Host Controller calculates the location of the next PTD header. The ISP1362 Host
Controller checks the payload size from the ‘Total size’ field of the PTD itself and
calculates the location of the next PTD header based on this information.
