Automatic UP/DOWN (however, when on 1 phase 1 input mode, UP/DOWN is
determined by a PC command or an input terminal.)
When 32-bit is specified: -2,147,483,648 to +2,147,483,647
When 16-bit is specified: 0 to 65,535 (upper limit can be user specified)
Each output is set when the present value of the counter matches with the compare
value (which is transferred from the PC), and is switched OFF by a reset command
from the PC.
YH
: Direct output processed by hardware.
YS
: Software processed output with worst delay time of 300
(Therefore, when the input frequency is 50 kHz, there is a worst case delay of 15 input
pulses.)
YHN
: NPN transistor output for YH output
YHP
: PNP transistor output for YH output
YSN
: NPN transistor output for YH output
YSP
: PNP transistor output for YH output
