MODE
Mode 0: 8-bit timer/counter TLx serves as 5-bit pre-scale.
Mode 1: 16-bit timer/counter, no pre-scale.
Mode 2: 8-bit timer/counter with auto-reload from THx.
Mode 3: (Timer 0) TL0 is an 8-bit timer/counter controlled by the standard Timer0
control bits. TH0 is an 8-bit timer only controlled by Timer1 control bits. (Timer 1)
Timer/Counter 1 is stopped.
FUNCTION
Gating control: When this bit is set, Timer/counter 1 is enabled only while the
pin is high and the TR1 control bit is set. When cleared, the
and Timer 1 is enabled whenever TR1 control bit is set.
Timer or Counter Select: When clear, Timer 1 is incremented by the internal clock.
When set, the timer counts falling edges on the T1 pin.
Timer 1 mode select bit 1. See table below.
Timer 1 mode select bit 0. See table below.
Gating control: When this bit is set, Timer/counter 0 is enabled only while the
pin is high and the TR0 control bit is set. When cleared, the INT0 pin has no
effect, and Timer 0 is enabled whenever TR0 control bit is set.
Timer or Counter Select: When clear, Timer 0 is incremented by the internal clock.
When set, the timer counts falling edges on the T0 pin.
Timer 0 mode select bit 1. See table below.
Timer 0 mode select bit 0. See table below.
FUNCTION
Timer 0 LSB.
