C8051F132 - UART Baud Rate config issue

Halo Frndz, Im using C8051F132 Silabs MCU .. I want to know that how to set UART1 baud rate..
I have came across few formula's.. but i didnt get the exact value.. My seniors done this configuration..Unfortunately they are here to clear my doubts.. i have seen our keil baud rate generator.,but i want to know that how it comes///

our program configuration contains:

void InitF132 (void)
{
  SFRPAGE       = TMR3_PAGE;
  TMR3CN        = 0x04;
  RCAP3L        = 0xCC;                 //F8CC=63692=1000 INT/SEC=1MS for 22.1184MHz
  RCAP3H        = 0xF8;

  SFRPAGE       = ADC0_PAGE;
  AMX0SL        = 0x07;
  ADC0CN        = 0x80;

  SFRPAGE       = TIMER01_PAGE;
  TMOD          = 0x20;
  TH1           = 0xA0;             //UART1 Baud rate 0xA0 = 9600, 0xD0 = 19200,22.1184MHz
  //CKCON       = 0x01;             //CLOCK Source = SYSCLK / 4
  TR1           = 1;

  SFRPAGE       = SPI0_PAGE;
  SPI0CFG       = 0x70;
  SPI0CN        = 0x0D;             //09
  SPI0CKR       = 0x0A;                 //SPI Clock Rate Register OSC/22=1000 khz

My ques is
1. What is the exact formula to find the baud rate & TH1 ?? (They have taken 8bit auto reload mode 2 timer 1 (TMOD))
2. Why there is no SCON intialization in it??
