CLR). Any attempt by the software to directly
write a 0 to this bit is ignored.
Timer Interrupt Source B Pending. See the de-
scription of TnAPND.
Timer Interrupt Source C Pending. See the de-
scription of TnAPND.
Timer Interrupt Source D Pending. See the de-
scription of TnAPND.
Timer Interrupt A Enable. When set (1), this bit
enables an interrupt on each occurrence of in-
terrupt condition “A.” When cleared (0), an oc-
currence of interrupt condition “A” does not
generate an interrupt to the CPU, but still sets
the associated pending flag (TnAPND). For an
explanation of interrupt conditions A, B, C, and
D, see Table15.
Timer Interrupt B Enable. See the description
of TnAIEN.
Timer Interrupt C Enable. See the description
of TnAIEN.
Timer Interrupt D Enable. See the description
of TnAIEN.

The Timer Interrupt Clear (TnICLR) register is a byte-wide,
write-only register that allows the software to clear the TnAP-
ND, TnBPND, TnCPND, and TnDPND bits in the Timer Inter-
rupt Control (TnICTRL) register. The register format is shown
below.

Timer Pending A Clear. When written with a 1,
the Timer Interrupt Source A Pending bit
(TnAPND) is cleared in the Timer Interrupt
Control register (TnICTL). Writing a 0 to the
TnACLR bit has no effect.
Timer Pending B Clear. See the description of
TnACLR.
Timer Pending C Clear. See the description of
TnACLR.
Timer Pending D Clear. See the description of
TnACLR.
