D[7:0] TR[7:0]: 8-bit Timer Reload Data
Set the initial value for the counter. (Default: 0x0)
The reload data written in this register is preset to the respective counter when the timer is reset or when
the counter underflows.
When starting the 8-bit timer after resetting, the timer counts down from the reload value. So the
reload value and the input clock frequency determine the period of time from starting the timer until
an underflow occurs (and between underflows). This makes it possible to obtain a desired wait time, a
periodical interrupt interval, or programmable transfer clock for the serial interface.
