46 / 149 page  46 3654A–MICRO–8/09 AT89LP428/828 Table 11-3. TMOD – Timer/Counter Mode Control Register TMOD Address = 089H Reset Value = 0000 0000B Not Bit Addressable GATE1 C/T1 T1M1 T1M0 GATE0 C/T0 T0M0 T0M1 Bit 765 43 210 Symbol Function GATE1 Timer 1 Gating Control. When set. Timer/Counter 1 is enabled only while INT1 pin is high and TR1 control pin is set. When cleared, Timer 1 is enabled whenever TR1 control bit isset. C/T1 Timer or Counter Selector 1. Cleared for Timer operation (input from internal system clock). Set for Counter operation (input from T1 input pin). C/T1 must be zero when using Timer 1 in PWM mode. T1M1 T1M0 Mode T1M1 T1M0 Timer 1 Operation 000 Variable 9 – 16-bit Timer mode. 8-bit Timer/Counter TH1 with TL1 as 1- to 8-bit prescaler. 101 16-bit Auto-reload mode. TH1 and TL1 are cascaded to form a 16-bit Timer/Counter that is reloaded with RH1 and RL1 each time it overflows. 210 8-bit Auto-reload mode. 8-bit Timer/Counter TL1 is reloaded from TH1 each time it overflows. 311 Timer/Counter 1 is stopped GATE0 Timer 0 Gating Control. When set. Timer/Counter 0 is enabled only while INT0 pin is high and TR0 control pin is set. When cleared, Timer 0 is enabled whenever TR0 control bit isset. C/T0 Timer or Counter Selector 0. Cleared for Timer operation (input from internal system clock). Set for Counter operation (input from T0 input pin). C/T0 must be zero when using Timer 0 in PWM mode. T0M1 T0M0 Mode T0M1 T0M0 Timer 0 Operation 000 Variable 9 – 16-bit Timer Mode. 8-bit Timer/Counter TH0 with TL0 as 1- to 8-bit prescaler. 101 16-bit Auto-reload mode. TH0 and TL0 are cascaded to form a 16-bit Timer/Counter that is reloaded with RH0 and RL0 each time it overflows. 210 8-bit Auto-reload mode. 8-bit Timer/Counter TL0 is reloaded from TH0 each time it overflows. 311 Split Timer Mode. TL0 is an 8-bit Timer/Counter controlled by the standard Timer 0 control bits. TH0 is an 8-bit timer only controlled by Timer 1 control bits. |
