Used to specify how to prescale the TIM and TLOWM counters in SMBTR. Counters are prescaled according to the following
formula
Clock cycles in clock high maximum count. Prescaled by SMBTR.EXP. Used for bus free detection. Used to time T
NOTE: Uses the prescaler specified by CWGR, NOT the prescaler specified by SMBTR.
Clock cycles in master maximum clock stretch count. Prescaled by SMBTR.EXP. Used to time T
Clock cycles in slave maximum clock stretch count. Prescaled by SMBTR.EXP. Used to time T
