Timer Interrupt
The 16-bit timer has the ability to generate an interrupt
on period match. When the timer count matches the
period register, the T1IF bit is asserted and an interrupt
will be generated, if enabled. The T1IF bit must be
cleared in software. The timer interrupt flag T1IF is
located in the IFS0 control register in the Interrupt
Controller.
When the Gated Time Accumulation mode is enabled,
an interrupt will also be generated on the falling edge of
the gate signal (at the end of the accumulation cycle).
Enabling an interrupt is accomplished via the respec-
tive timer interrupt enable bit, T1IE. The timer interrupt
enable bit is located in the IEC0 control register in the
Interrupt Controller.
