Preliminary W77IC32
Publication Release Date: March 2000
- 21 - Revision A0
otherwise timer 2 overflow is used. Setting this bit forces timer 2 in baud rate generator
mode.
EXEN2: Timer 2 External Enable. This bit enables the capture/reload function on the T2EX pin if
Timer 2 is not generating baud clocks for the serial port. If this bit is 0, then the T2EX pin
will be ignored, otherwise a negative transition detected on the T2EX pin will result in
capture or
reload.
TR2:
Timer 2 Run Control. This bit enables/disables the operation of timer 2. Clearing this bit will
halt the timer 2 and preserve the current count in TH2, TL2.
C/
T2
: Counter/Timer Select. This bit determines whether timer 2 will function as a timer or a
counter. Independent of this bit, the timer will run at 2 clocks per tick when used in baud rate
generator mode. If it is set to 0, then timer 2 operates as a timer at a speed depending on
T2M bit (CKCON.5), otherwise it will count negative edges on T2 pin.
CP/
RL2
:Capture/Reload Select. This bit determines whether the capture or reload function will be
used for timer 2. If either RCLK or TCLK is set, this bit will be ignored and the timer will
unction in an auto-reload mode following each overflow. If the bit is 0 then auto-reload will
occur when timer 2 overflows or a falling edge is detected on T2EX pin if EXEN2 = 1.
If this bit is 1, then timer 2 captures will occur when a falling edge is detected on T2EX pin if
EXEN2 = 1.

HC5:
Hardware Clear INT5 flag. Setting this bit allows the flag of external interrupt 5 to be
automatically cleared by hardware while entering the interrupt service routine.
Hardware Clear INT4 flag. Setting this bit allows the flag of external interrupt 4 to be
automatically cleared by hardware while entering the interrupt service routine.
HC4:
HC3:
Hardware Clear INT3 flag. Setting this bit allows the flag of external interrupt 3 to be
automatically cleared by hardware while entering the interrupt service routine.
Hardware Clear INT2 flag. Setting this bit allows the flag of external interrupt 3 to be
automatically cleared by hardware while entering the interrupt service routine.
T2CR: Timer 2 Capture Reset. In the Timer 2 Capture Mode this bit enables/disables hardware
automatically reset Timer 2 while the value in TL2 and TH2 have been transferred into the
capture register.
T2OE: Timer 2 Output Enable. This bit enables/disables the Timer 2 clock out function.
DCEN: Down Count Enable: This bit, in conjunction with the T2EX pin, controls the direction that
timer 2 counts in 16-bit auto-reload mode.
