MBTC0 - Multi-Block Transfer Control 0 - (read/write 12h)
This register is available for W88111AF only to specify the behavior of multi-block transfer logic. The
host interface supports multi-block transfer without microprocessor intervention by following
sequence:
MBC[4:0]
←
the number of block to be transferred minus 1 (ex. 3)
TBCL (02h), TBCH (03h)
←
the number of bytes/words to be transferred in each block
minus 1 (ex. 1175)
TACL (04h), TACH (05h)
←
the starting point of the block (ex. F4h, FFh)
TBL (24h), TBH (25h)
←
the RAM block number of the first block to be transferred (ex. 5)
ATBLO (34h), ATBLH (35h)
←
the total bytes to be transferred (ex. 9408)
ADTT (17h.4)
←
1
PS: STBCEN (18h.3) should not be set in multi-block transfer operation.
When ADTT is set, host will receive HIRQ, check status, and then start to read data.
After the last bytes/words of one block (except the last one) is read by the host, the following
hardware sequence is executed:
TBCL (02h), TBCH (03h)
←
reload
TACL (04h), TACH (05h)
←
reload
TBL (24h), TBH (25h)
←
auto-increment
MBC[4:0]
←
auto-decrement
TENDb only becomes active at the end of data transfer of the last block.
Bit 7: MBVAb - Multi-Block Counter Valid Flag
This bit is used to indicate that Multi-Block Counter MBC[4:0] is stable enough to be monitored by
microprocessor.
