8.4.3 Timer Registers
The timer registers (TRH and TRL), shown in
Figure 8-4
, contains the
current high and low bytes of the 16-bit counter. Reading TRH before
reading TRL causes TRL to be latched until TRL is read. Reading TRL
after reading the timer status register clears the timer overflow flag
(TOF). Writing to the timer registers has no effect.
