* 1 : Subcommand is for the QnA-compatible 3E frame.
* 2 : Devices such as TS, TC, SS, SC, CS, and CC cannot be specified in units of words. For the
monitor registration, an error (4032
* 3 : During monitor registration, monitor condition cannot be set.
* 4 : Do not execute monitor registration from multiple external devices. If executed, the last monitor
registration becomes valid.
* 5 : Set the number of processed points so that the following condition is satisfied.
(Number of word access points)
• Bit devices are regarded as 16 bits during word access and 32 bits during double-word access.
• Word devices are regarded as one word during word access and two words during double-word
access.
