1. Value of this parameter depends on prescacler ratio defined in bits 0,1 and 7 of SCON Register.In the above table, the ratio
used is 4. As it can be set also to 8, 16, 32, 64 or 128, the factor of TPER must be changed according to the new ratio.E.g.
2TPER-20ns(1) will be changed to 4TPER-20ns(1) if the prescaler ratio equals 8.
