TROUBLESHOOTING
*14: The Universal model QCPU except the Q02UCPU.
*15: The range is from 1 to 9 for the Q03UDCPU, Q04UDHCPU, and Q06UDHCP whose first 5 digits of serial number is "10012" or earlier.
(Default: 2 Or when setting other than 1 to 9, the register operates as 9).

• Specifies the maximum number of blocks used for the multiple CPU
high-speed transmission dedicated instruction (target CPU=CPU No.1).
When the dedicated instruction of Multiple CPU transmission is
executed to the CPU No.1, and the number of empty blocks of the
dedicated instruction transmission area is less than the setting value of
this register, SM796 is turned ON, which is used as the interlock signal
for consecutive execution of the dedicated instruction of Multiple CPU
transmission.
