9.5 I/O Registers
The following registers control and monitor the timer operation:
Timer status and control register (TSCR)
Timer counter register (TCR)
9.5.1 Timer Status and Control Register
The read/write timer status and control register performs the following functions:
Flags timer interrupts
Enables timer interrupts
Resets timer interrupt flags
Selects real-time interrupt rates
TOF — Timer Overflow Flag
This read-only flag becomes set when the first eight stages of the counter roll over from $FF to $00.
TOF generates a timer overflow interrupt request if TOIE is also set. Clear TOF by writing a logic 1 to
the TOFR bit. Writing to TOF has no effect. Reset clears TOF.
RTIF — Real-Time Interrupt Flag
This read-only flag becomes set when the selected RTI output becomes active. RTIF generates a
real-time interrupt request if RTIE is also set. Clear RTIF by writing a logic 1 to the RTIFR bit. Writing
to RTIF has no effect. Reset clears RTIF.
TOIE — Timer Overflow Interrupt Enable Bit
This read/write bit enables timer overflow interrupts. Reset clears TOIE.
1 = Timer overflow interrupts enabled
0 = Timer overflow interrupts disabled
RTIE — Real-Time Interrupt Enable Bit
This read/write bit enables real-time interrupts. Reset clears RTIE.
1 = Real-time interrupts enabled
0 = Real-time interrupts disabled
TOFR — Timer Overflow Flag Reset Bit
Writing a logic 1 to this write-only bit clears the TOF bit. TOFR always reads as logic 0. Reset clears
TOFR.
RTIFR — Real-Time Interrupt Flag Reset Bit
Writing a logic 1 to this write-only bit clears the RTIF bit. RTIFR always reads as logic 0. Reset clears
RTIFR.
