BENTLY 3500/60 163179-01通过将“0”写入适当的“定时器”，可以清除特定的定时器中断x由IRQ“字段引起。或者，写入适当的定时器x IRQ Clear（TxIC）寄存器也将清除中断。当使用“定时器x”清除中断时引起IRQ”字段，请注意，确保使用正确位掩码非常重要以使其他寄存器设置不受影响。

优选的清算方法中断使用第52页所述的“定时器x IRQ清除”寄存器。BENTLY 3500-60 163179-01定时器控制状态寄存器2（TCSR2）定时器也由定时器控制状态寄存器2（TCSR2）中的位控制位于BAR2中地址的偏移量0x04处。

此字段中位的映射寄存器如下：“读锁存选择”位用于选择可编程存储器的锁存模式定时器。如果该位设置为“0”，则在读取任何一个时，每个定时器输出都被锁存它的地址。例如，对TMRCCR12寄存器的读取会锁存定时器1和2。对TMRCCR3寄存器的读取锁存定时器3的计数。这对这些寄存器中的任何一个的每次读取都继续。

因此，不可能在给定实例中及时捕获所有四个计时器的值。然而此位为“1”，所有四个定时器输出将仅在定时器1和2的读取时锁存当前计数寄存器（TMRCCR12）。因此同时使用四个定时器，首先执行对TMRCCR12的读取（使用32位读取），然后读取TMRCCR3和TMRCCR4TMRCCR12寄存器）导致同时锁存所有四个定时器值。这个对TMRCCR3和TMRCCR4寄存器的后续读取不会锁存新计数值，允许获得同一时间实例中所有定时器的计数。

BENTLY 3500/60 163179-01 By writing "0" to the appropriate "timer", it is possible to clear specific timer interrupts x caused by the IRQ "field. Alternatively, writing the appropriate timer x IRQ Clear (TxIC) register will also clear the interrupt. When using the "Raise IRQ when Timer x" field to clear interrupts, note that it is important to ensure that the correct bitmask is used so that other register Settings are not affected.

The preferred clearing method interrupts using the "timer x IRQ Clear" register described on page 52. BENTLY 3500-60 163179-01 Timer Control Status Register 2 (TCSR2) The timer is also controlled by bits in Timer Control Status register 2 (TCSR2) located at the offset 0x04 of the address in BAR2.

The mapping register for the bits in this field is as follows: The "Read latch selection" bit is used to select a latch-mode timer for programmable memory. If this bit is set to "0", each timer output is latched to its address when either is read. For example, a read of the TMRCCR12 register latches timers 1 and 2. Count of the read latch timer 3 of the TMRCCR3 register. Each read of any of these registers continues.
