2 new blocks have arrived in BL/BP (C

) and a new block (A

)
has entered the decoder buffer. Hence, DOVF is set again.
To prevent this, an extra read must be performed after reading (a)
dashed line shows what would happen if no read
occurred at (a). DOVF bit set until the next read of BP
register, however D1, A2 would be lost
