<5th byte>
The 5th byte selects a parameter to be output to the EXT pin (logic operation monitor pin). Input data to bits D0 to
D6 of this byte. Bit D7 is fixed to “0”.
There are two EXT pins. EXTα indicates the operating status of α ch, and EXTβ indicates that of β ch. The
relationship between each bit and each EXT pin is as shown in Table 5-4.

The checksum bit is cleared to “0” in the event of an error. Normally, it is “1”.
If two or more signals that output signals to EXTα and EXTβ are selected, they are positively ORed for output.
Caution The CHOPPING signal is not output in internal oscillation mode.
