Timer Control Register Definitions
PS019921-0308
Reading the Timer Count Values
Timer Output Signal Operation
Timer 0-3 High and Low Byte Registers
6. Write to the Timer Control 1 register to enable the timer.
7. Counting begins on the first appropriate transition of the Timer Input signal. No
In m/COMPARE mode, the elapsed time from timer start to Capture event can be calcu-
lated using the following equation:
The current count value in the timers can be read while counting (enabled). This capability
has no effect on timer operation. When the timer is enabled and the Timer High Byte
register is read, the contents of the Timer Low Byte register are placed in a holding
register. A subsequent read from the Timer Low Byte register returns the value in the
holding register. This operation allows accurate reads of the full 16-bit timer count value
while enabled. When the timers are not enabled, a read from the Timer Low Byte register
returns the actual value in the counter.
Timer Output is a GPIO Port pin alternate function. Generally, the Timer Output is toggled
every time the counter is reloaded.
Timers 0-2 are available in all packages. Timer 3 is only available in the 64-, 68-, and
80-pin packages.
The Timer 0-3 High and Low Byte (TxH and TxL) registers (see
page 87) contain the current 16-bit timer count value. When the timer is enabled, a read
from TxH causes the value in TxL to be stored in a temporary holding register. A read
from TMRL always returns this temporary register when the timers are enabled. When the
timer is disabled, reads from the TMRL reads the register directly.
Writing to the Timer High and Low Byte registers while the timer is enabled is not
recommended. There are no temporary holding registers available for write operations, so
simultaneous 16-bit writes are not possible. If either the Timer High or Low Byte registers
are written during counting, the 8-bit written value is placed in the counter (High or Low
Byte) at the next clock edge. The counter continues counting from the new value.
Timer 3 is unavailable in the 44-pin packages.
Capture Elapsed Time (s)
interrupt is generated by this first edge.
