Section 8: TIMER SYSTEM
MC68HC05G3 (705G4) Specification Rev. 1.1
8.5.3
OUTPUT COMPARE REGISTER 2 (OC2)
READ:
anytime
WRITE:
anytime
The data in the OC2 register is transferred to the buffer register when the CPU writes to the
TCNT2, when the CMP2 presets the TCNT2, or when the system resets.
When the OC2 buffer register matches the TCNT2 register, the OC2F bit in the TSR2
register is set and TCNT2 is preset to $01. OC2 is preset to $FF on reset.
8.5.4
TIMER COUNTER 2 (TCNT2)
READ:
anytime
WRITE:
anytime (TCNT2 becomes $01 by any write data)
The timer counter 2 (TCNT2) is incremented by the falling edge of the timer clock (which is
synchronized and has the same timing as the falling edge of PHI2).
The TCNT2 register is compared with the OC2 buffer register and initialized to $01 if it
matches.
This counter also is initialized to $01 by reset or any CPU write to this register. The CPU
read of this counter should be done while PHI2 is high and data may be latched by the local
or main data bus while PHI2 is low.
