2.1.4 High Speed Counter and High Speed Pulse Output
MK provides 4 high speed counters (HSC0~HSC3).High speed counter supports a variety of
modes, it can be single-phase, dual-phase (Up/Down), AB phase (1-fold and 4-fold
frequency).The maximum counting frequency of the four pulse counters is 50KHz.

MK070E also provides 4 high speed pulse outputs(Q0.0,Q0.1,Q0.4andQ0.5)and all support
PTO(pulse train) and PWM(pulse width modulation) output.The highest frequency of each
series of CPU is as follows(The resistor of load should be less than 3KΩ).

2.1.5 Edge Interrupts
I0.0-I0.3 in CPU support edge interrupt function, it can execute interrupt by rising edge and
falling edge of input signal. By using this function, it can capture the rising edge and falling
edge of input signal quickly. For some input signal whose pulse width is less than the CPU
scan time, it can respond quickly.
2.1.6 Data Retentive and Data Backup
Data retentive means the data in RAM can retain after power failure.CPU provides a lithium
battery (Replaceable but un-rechargeable) for data retentive. When CPU loses power, the data
in the RAM will be maintained by the lithium battery, and the retentive ranges will be left
unchanged at next power on.Through [Hardware] configuration in KincoBuilder, user can
select the type of data retentive (Such as V,C area) and the range. The life of battery is 5 years
and the retaining duration is 3 years at normal temperature.
