Description
Timer 2 Overflow Flag.
Set by hardware on a Timer 2 overflow. TF2 cannot be set when either RCLK = 1 or TCLK = 1.
Cleared by user software.
Timer 2 External Flag.
Set by hardware when either a capture or reload is caused by a negative transition on T2EX
and EXEN2 = 1.
Cleared by user software.
Receive Clock Enable Bit.
Set by the user to enable the serial port to use Timer 2 overflow pulses for its receive clock in
serial port Modes 1 and 3.
Cleared by the user to enable Timer 1 overflow to be used for the receive clock.
Transmit Clock Enable Bit.
Set by the user to enable the serial port to use Timer 2 overflow pulses for its transmit clock in
serial port Modes 1 and 3.
Cleared by the user to enable Timer 1 overflow to be used for the transmit clock.
Timer 2 External Enable Flag.
Set by the user to enable a capture or reload to occur as a result of a negative transition on
T2EX if Timer 2 is not being used to clock the serial port.
Cleared by the user for Timer 2 to ignore events at T2EX.
Timer 2 Start/Stop Control Bit.
Set by the user to start Timer 2.
Cleared by the user to stop Timer 2.
Timer 2 Timer or Counter Function Select Bit.
Set by the user to select the counter function (input from external T2 pin).
Cleared by the user to select the timer function (input from on-chip core clock).
Timer 2 Capture/Reload Select Bit.
Set by the user to enable captures on negative transitions at T2EX if EXEN2 = 1.
Cleared by the user to enable autoreloads with Timer 2 overflows or negative transitions at
T2EX when EXEN2 = 1. When either RCLK = 1 or TCLK = 1, this bit is ignored and the timer is
forced to autoreload on Timer 2 overflow.
