The following register divides the APB clock frequency to use for all of
the timers. The value in the register picks a power of two value from a
free running 16-bit counter that serves as an enable for the timers.

API2C Timer Load Value
This value loads into the timer at the beginning of every
data byte transfer to or from the API2C interface (Start or
ACK of previous byte). When the timer is enabled and the
master controller extends the SCL signal by asserting the
SCL hold signal, the timer counts down from the timer
value at the divided clock rate. If the timer reaches 0, the
device sets the time-out flag. Following a time-out, the
timer reloads the Timer Load Value at the beginning of
the next data byte transfer.
The software programs this value for a certain time-out
period, depending on the APB clock frequency, and
according to the following formula:
