When the I/O termianl is "L" and the CE tarminal is "H", timer data can read out. The output is LSB first and the
The timer data is transferred from timer counter to shift register at rising edge of the chip enable on the CE
Afterward the timer data in the shift register shift by synchronized at the falling edge of clock signal on the CLK
