11.2.3 TIMER INTERRUPT FLAG REGISTER (TM2IR)

Table 22 Timer Interrupt Flag register (address C8H)

Table 23 Description of the TM2IR bits (see notes 1 and 2)

Notes

1. Interrupt Enable IEN1 is used to enable/disable Timer 2 interrupts (see Section 14.1.2).

2. Interrupt Priority Register IP1 is used to determine the Timer 2 interrupt priority (see Section 14.1.4).

11.2.4 S

ET ENABLE REGISTER (STE)

Table 24 Set Enable register (address EEH)

Table 25 Description of the STE bits (see notes 1 and 2)

Notes

1. If STE.n is LOW then P4.n is not affected by a match of CM0 and T2 (n = 0, 1, 2, 3, 4, 5).

2. STE.6 and STE.7 are read only.
