After the last word of one block (except the last one) is read by the host, the following hardware sequence is
executed:
TWCH/L (03h/02h)
reload
TACH/L (05h/04h)
reload
TBH/L (25h/24h)
auto-increment
MBC0 (12h.4-0)
auto-decrement
Flag
TENDb (01h.r6)
only becomes active at the end of data transfer of the last block. This register is 0 after
chip reset, host reset and firmware reset.

Bit 7:
MBVAb - Multi-Block Counter Valid Flag
This bit is used to indicate that
MBC (12h.4-0)
is stable enough to be monitored by microprocessor.
There is no need to monitor this bit in normal operation.
Bit 6:
MBINC - Multi-Block Increment Flag
This bit becomes active-high if microprocessor sets
INCMBC (13h.w0)
and multi-block number
increment has not completed. There is no need to monitor this bit in normal operation.
Bit 4-0: MBC[4:0] - Multi-Block Counter
Before triggering multi-block transfer, the number of blocks to be transferred minus 1 should be
written to
MBC (12h.4-0)
. Single block transfer is performed if
MBC (12h.4-0)
is zero. There is no
need to monitor this counter normal operation.
