TF2—Timer 2 Overflow Flag. This bit is set by the MCU when Timer 2 over-
flows from FFFF
H
back to 0000
H
. When enabled, this bit causes a Timer 2 in-
terrupt. Cleared by software. This bit is not set when TCLK or RCLK is set.
EXF—Timer 2 External Flag. This bit is set by the MCU when a timer capture
or reload is triggered by a 1-0 transition on T2EX. When enabled, this bit
causes a Timer 2 interrupt. Cleared by software.
RCLK—Timer 2 Receive Clock. When this bit is set, Timer 2 provides the se-
rial port receive baud rate clock.
TCLK—Timer 2 Transmit Clock. When this bit is set, Timer 2 provides the
serial port transmit baud rate clock.
EXEN2—Timer 2 External Enable. When this bit is set, a capture or reload
is triggered on a 1-0 transition on the T2EX line.
TR2—Timer 2 Run Control. When this bit is set, Timer 2 is activated/run.
When this bit is clear, Timer 2 is stopped.
C/T2—Counter/Interval Timer. When this bit is set, Timer 2 acts as an event
counter based on external stimulus on the T2EX line. When this bit is clear,
Timer 2 acts as an interval timer.
CP/RL2C—Capture/Reload. When set, a capture occurs on a 1-0 transition
of T2EX. When clear, a reload occurs on timer overflow or on a 1-0 transition
of T2EX. This bit is only relevant if EXEN2 is set, and does not apply if RCLK
or TCLK are set.
