For the monitor registration, an error (4032
*3 The monitor condition specification cannot be used for these commands.
*4 Do not execute monitor registration from multiple external devices. If executed, the last monitor registration becomes
valid.
*5 Set the number of processing points within the range of the following calculation formula.
(number of word access points)  12 + (number of double word access points)  14  960
• One point of a bit device corresponds to 16 bits for word access or to 32 bits for double word access.
• One point of a word device corresponds to one word for word access or to two words for double word access.
