*t1 = 2 x (crystal period) for clock frequencies other than 20 MHz.
*t2,t7 = 8 x (crystal period) for clock frequencies other than 20 MHz. This period applies to data of two consecutive one's.
**t4: For clock frequencies other than 20 MHz, t4 = 18 x (crystal period)+ 50 nsec.
**t5: For clock frequencies other than 20 MHz, t5 = 6 x (crystal period)+ 50 nsec.
