定时器2 IRQ清除（T2IC）定时器2 IRQ-清除（T2IC）寄存器用于清除定时器2引起的中断。写入此寄存器（位于BAR2中地址的偏移量0x34处）会导致定时器2的中断被清除。这也可以通过将“0”写入定时器控制状态寄存器（CSR1）的相应“定时器x引起的IRQ”字段来完成。该寄存器是只读的，写入的数据是无关的。定时器3 IRQ清除（T3IC）定时器3 IRQ-清除（T3IC）寄存器用于清除定时器3引起的中断。写入此寄存器（位于BAR2中地址的偏移量0x38处）会导致计时器3的中断被清除。这也可以通过将“0”写入定时器控制状态寄存器（CSR1）的相应“定时器x引起的IRQ”字段来完成。该寄存器是只读的，写入的数据与定时器4 IRQ清除（T4IC）无关。定时器4 IRQ-清除（T4IC）寄存器用于清除定时器4引起的中断。写入此寄存器（位于BAR2中地址的偏移量0x3C处），将清除定时器4的中断。这也可以通过将“0”写入定时器控制状态寄存器（CSR1）的相应“定时器x引起的IRQ”字段来完成。该寄存器是只读的，写入的数据是无关的。
Timer 2 IRQ Clear (T2IC)
The Timer 2 IRQ Clear (T2IC) register is used to clear an interrupt caused by Timer 2.
Writing to this register, located at offset 0x34 from the address in BAR2, causes the
interrupt from Timer 2 to be cleared. This can also be done by writing a “0” to the
appropriate “Timer x Caused IRQ” field of the timer Control Status Register (CSR1).
This register is write only and the data written is irrelevant.
Timer 3 IRQ Clear (T3IC)
The Timer 3 IRQ Clear (T3IC) register is used to clear an interrupt caused by Timer 3.
Writing to this register, located at offset 0x38 from the address in BAR2, causes the
interrupt from Timer 3 to be cleared. This can also be done by writing a “0” to the
appropriate “Timer x Caused IRQ” field of the timer Control Status Register (CSR1).
This register is write only and the data written is irrelevant Timer 4 IRQ Clear (T4IC)
The Timer 4 IRQ Clear (T4IC) register is used to clear an interrupt caused by Timer 4.
Writing to this register, located at offset 0x3C from the address in BAR2, causes the
interrupt from Timer 4 to be cleared. This can also be done by writing a “0” to the
appropriate “Timer x Caused IRQ” field of the timer Control Status Register (CSR1).
This register is write only and the data written is irrelevant.
