
SMBus Timing Control
The SMBCS1–0 bits in SMB0CF select the SMBus clock source



Overflows from Timer 0, Timer 1 or Timer 2 set the time-base
Used only when operating as a Master or when the Bus Free Timeout detection
is enabled
Selected clock source may be shared by other peripherals so long as the timer is
left running at all times.
•Example, Timer 1 overflows may generate the SMBus and UART baud rates
simultaneously
Timer overflow rate determines high and low
time and must conform to the standards as
well as the requirements of the system, i.e.
not driven or extended by another device)
T
HIGH
Actual bit rate of the peripheral
typically twice as large as T
bus loading affects timing.
LOW
