2 : DREQ mask bit
(Refer to
description of
commands.)
Note 1) The default values of flags (F0-F7) and bits (B0-B6) are zero (0).
2) When using an extended system, store the second word of the operation mode setting command following the transmit
repeat request command.
3) It is impossible to control mode inversion with operation mode setting command and extended toggle input (TOG)
together.
