CUnet Family MKY44-IO32A
Occupied Memory Block
The PWM and Up/Down counter mode of the MKY44-IO32A occupies the MB (Memory Block) of the SA value that is set by SA0
to SA5 of the ST44SW.
In bits 0 to 23 of the MB occupied by the PWM and Up/Down counter mode of the MKY44-IO32A, the value of Counter-0 is stored.
In bits 24 to 31, the status of the general-purpose input pins (Di0 to Di7) is stored. In bits 32 to 55, the value of Counter-1 is stored.
In bits 56 to 63, the status of the general-purpose output pins (Do0 toDo7) is stored.
OFF, the latest value loaded in each CUnet cycle

For the status of the general-purpose input pins
The values read out from Counter-0 and Counter-1 are as follows.
Range of values : 0x000000 to 0xFFFFFF
Initial value : 0x000000 (Right after power-on, hardware reset, and CLR(#CLR0 or #CLR1) signal input)
Overflow operation : MKY44-IO32A continues counting.
Up counter mode : 0xFFFFFF is reset to start recount from 0x000000.
Down counter mode : 0x000000 is reset to start recount from 0xFFFFFF.
Note : You cannot set any values as the initial value of the counter.
Note : When you read the Counter-0 and Counter-1 values using CUnet master, use the hazard protection function of CUnet master.
the digital filter will be stored.
