TIMERS
7.4
Control Registers for Timer A and Timer B
Timer A and Timer B are enabled/disabled via the CETA (Count Enable Timer A) and CETB (Count
Enable Timer B) control bits in the Timer Control Register ($000C).
CETA, CETB
1 (set)
–
Counter enabled
0 (clear) –
Counter disabled
Both timers generate a signal on overow which can be used to interrupt the processor. These
signals can be masked by the INTMA and INTMB bits in the Interrupt Control Register ($000E).
Timer Interrupt Flag and Acknowledge bits INTFA and INTFB indicate when a timer interrupt has
occurred and can be written to reset the timer interrupt logic.
INTMA, INTMB
1 (set)
–
Interrupts not masked
0 (clear) –
Interrupts masked
INTFA, INTF
1 (set)
–
Interrupt has occurred
0 (clear) –
Interrupt has not occurred
Writing a “0” to INTFA or INTFB acknowledges the interrupt and resets the interrupt signal for that
timer.
