Section 8: TIMER SYSTEM
MC68HC05G3 (705G4) Specification Rev. 1.1
8.3
PRESCALER
The 8-bit prescaler in the timer system divides the system clock (PHI2) and provides the
divided clock to timers and event input. The 3-bit prescaler provides divided clock to the
PWM. See Figure 8-6: Prescaler Block Diagram.
CLK1 for the timer 1 is a fixed frequency clock (PHI2/4).
CLK2 for the timer 2 is selected by the T2R1 and T2R0 bits in the TBCR1, and this clock is
used at the event input for the gate mode. The CLK2 transitions must be synchronous to
the falling edge of PHI2.
CLK3 for the PWM is selected by the T3R1 and T3R0 bits in the TBCR1, and this clock is
for the PWM counter. The CLK3 transitions must be synchronous to the falling edge of
PHI2.
Figure 8-6: Prescaler Block Diagram
8.4
TIMER I/O PINS
Two input (TCAP and EVI) and two output (TCMP and EVO) pins are reserved for the
timers.
8.4.1
TIMER INPUT 1 (TCAP)
This input pin is used for the input capture of timer 1. Active input edge (rising edge or falling
edge) is selected by the IEDG bit in the TCR. Since the TCAP pin is shared with the PC3
I/O pin, changing the state of the DDRC3 or data register can cause an unwanted TCAP
interrupt. This can be handled by clearing the ICIE bit before changing the configuration of
PC3 and clearing any pending interrupts before enabling ICIE.
