;Every cycle length is the same to power cycle, we also use the power cycle to guide the
;relay off time(30sec.)
;
;
;This version have the study mode and keep relay warming mode. 
;For the ATtiny11 have no eeprom in it so we need to catch the zerocross as soon as possible.
;keep the relay's coil warming in order to keep the zero cross from moving 
;after a long time of relay opens.
;A more exact of initial delay (TCNT0)is 130 at 50HZ and 180 at 60HZ.
;In the new BZ50 we have modify it adjust the different 
;AC power input voltage phase frequence.
;we made it can load different type of load also have the zero cross. 
;Such as ballast fluorescent and incandescence.
