Product data sheet
The INTL and ATL buffers use ‘blocked memory management’ scheme to enhance the
status and control capability of each and every individual Philips Transfer Descriptor
(PTD) structure. The INTL and ATL buffers are further divided into blocks of equal sizes,
depending on the value written to the HcATLBlkSize register (ATL) and the HcINTLBlkSize
register (INTL). The ISP1362 Host Controller supports up to 32 blocks in the ATL and
INTL buffers. Each of these blocks can be used for one complete PTD data.
Note that the block size does not include the 8 bytes PTD header and is strictly the size of
the payload. Both the ATL and INTL block sizes must be a multiple of double word
(4 bytes).
