Used to specify how to prescale the TWCK clock. Counters are prescaled according to the following formula
Clock cycles for data setup and hold count. Prescaled by CWGR.EXP. Used to time T
Clock cycles in clock high count. Prescaled by CWGR.EXP. Used to time T
Clock cycles in clock high count. Prescaled by CWGR.EXP. Used to time T
Clock cycles in clock low count. Prescaled by CWGR.EXP. Used to time T
