Section 3 Operating Modes
3.1 Operating Mode Selection
The SH7065 has ten operating modes. The settings of the mode pins (MD5 to MD0) determine the
mode in which the chip operates. The mode pin settings must not be changed while the chip is
operating (while power is being supplied).
The method of selecting the operating mode is shown in table 3.1
