The T2CON timer 2 control register is a bitaddressable register which controls the timer 2 function
and the compare mode of registers CRC, CC1 to CC3.
Special Function Register T2CON (Address C8H)
Reset Value : 00H
Bit
Function
T2PS
Prescaler select bit
When set, timer 2 is clocked in the “timer“ or “gated timer“ function with 1/24 of the
oscillator frequency. When cleared, timer 2 is clocked with 1/12 of the oscillator
frequency. T2PS must be 0 for the counter operation of timer 2.
I3FR
External interrupt 3 falling/rising edge flag
Used for capture function in combination with register CRC. lf set, a capture to
register CRC (if enabled) will occur on a positive transition at pin P1.0 / INT3 / CC0.
lf I3FR is cleared, a capture will occur on a negative transition.
T2R1
T2R0
Timer 2 reload mode selection
T2CM
Compare mode bit for registers CRC, CC1 through CC3
When set, compare mode 1 is selected. T2CM = 0 selects compare mode 0.
