INTCTRLB - Interrupt Enable Register B
CTRLFCLR/CTRLFSET - Control Register F Clear/Set
• Bit 3:2 - ERRINTLVL[1:0]:Timer Error Interrupt Level
These bits enable the Timer Error Interrupt and select the interrupt level as described in
rupts and Programmable Multi-level Interrupt Controller” on page
• Bit 1:0 - OVFINTLVL[1:0]:Timer Overflow/Underflow Interrupt Level
These bits enable the Timer Overflow/Underflow Interrupt and select the interrupt level as
described in
• Bit 7:0 - CCxINTLVL[1:0] - Compare or Capture x Interrupt Level:
These bits enable the Timer Compare or Capture Interrupt and select the interrupt level as
described in
This register is mapped into two I/O memory locations, one for clearing (CTRLxCLR) and one for
setting the register bits (CTRLxSET) when written. Both memory locations yield the same result
when read.
The individual status bit can be set by writing a one to its bit location in CTRLxSET, and cleared
by writing a one to its bit location in CTRLxCLR. This each bit to be set or cleared without using
of a Read-Modify-Write operation on a single register.
• Bit 7:4 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 3:2 - CMD[1:0]: Timer/Counter Command
These command bits can be used for software control of update, restart, and reset of the
Timer/Counter. The command bits are always read as zero.
