定時(shí)器2 IRQ清除（T2IC）定時(shí)器2 IRQ-清除（T2IC）寄存器用于清除定時(shí)器2引起的中斷。寫(xiě)入此寄存器（位于BAR2中地址的偏移量0x34處）會(huì )導致定時(shí)器2的中斷被清除。這也可以通過(guò)將“0”寫(xiě)入定時(shí)器控制狀態(tài)寄存器（CSR1）的相應“定時(shí)器x引起的IRQ”字段來(lái)完成。該寄存器是只讀的，寫(xiě)入的數據是無(wú)關(guān)的。定時(shí)器3 IRQ清除（T3IC）定時(shí)器3 IRQ-清除（T3IC）寄存器用于清除定時(shí)器3引起的中斷。寫(xiě)入此寄存器（位于BAR2中地址的偏移量0x38處）會(huì )導致計時(shí)器3的中斷被清除。這也可以通過(guò)將“0”寫(xiě)入定時(shí)器控制狀態(tài)寄存器（CSR1）的相應“定時(shí)器x引起的IRQ”字段來(lái)完成。該寄存器是只讀的，寫(xiě)入的數據與定時(shí)器4 IRQ清除（T4IC）無(wú)關(guān)。定時(shí)器4 IRQ-清除（T4IC）寄存器用于清除定時(shí)器4引起的中斷。寫(xiě)入此寄存器（位于BAR2中地址的偏移量0x3C處），將清除定時(shí)器4的中斷。這也可以通過(guò)將“0”寫(xiě)入定時(shí)器控制狀態(tài)寄存器（CSR1）的相應“定時(shí)器x引起的IRQ”字段來(lái)完成。該寄存器是只讀的，寫(xiě)入的數據是無(wú)關(guān)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.
