MEC Control Register

MATRA MHS
Rev. D (10 Apr. 97)
The scaler shall be set to: Scaler = Clock/(32*Baudrate*(2-UBR))-1
Where Clock is either the frequency of the system clock (SYSCLK) or the watchdog clock (WDCLK) selected by UCS (bit
23 in MEC Control Register). UBR is the value of the UBR bit. Baudrate is the desired baudrate. Note that the resulting
actual baudrate will probably not be exactly the desired one. This is due to the fact that Scaler is an integer number, and
the above given equation may yield a non-integer result, depending on the Clock frequency.
