General Release Specification
Timer I/O Registers
MC68HC705C9A — Rev. 2.0
Capture/Compare Timer
8.4.3 Timer Registers (TRH and TRL)
The timer registers, 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.
