Used to specify how to prescale the SMBus TLOWS counter. The counter is prescaled according to the following formula:
Non-prescaled clock cycles for data setup count. Used to time T
This timing is used for timing the ACK/NAK bits, and any data bits driven in slave transmitter mode.
Prescaled clock cycles used to time SMBus T
