定時(shí)器4電流計(jì)數(shù)寄存器(TMRCCR4)定時(shí)器4的電流計(jì)數(shù)可通過(guò)定時(shí)器4電流計(jì)數(shù)器寄存器(TMRC-CR4)讀取,該寄存器位于BAR2中地址的偏移量0x28處。此寄存器中的位映射如下:讀取此字段時(shí),鎖存并返回當(dāng)前計(jì)數(shù)值。根據(jù)WDT控制狀態(tài)寄存器(CSR2)中“讀取鎖存選擇”位的設(shè)置,有兩種模式?jīng)Q定如何鎖存計(jì)數(shù)。有關(guān)這兩種模式的更多信息,請(qǐng)參閱CSR2寄存器說(shuō)明。定時(shí)器1 IRQ清除(T1IC)定時(shí)器1 IRQ-清除(T1IC)寄存器用于清除定時(shí)器1引起的中斷。寫(xiě)入此寄存器(位于BAR2中地址的偏移量0x30處),將清除計(jì)時(shí)器1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(yīng)“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(shù)據(jù)是無(wú)關(guān)的。
Timer 4 Current Count Register (TMRCCR4)
The current count of Timer 4 may be read via the Timer 4 Current Count Register
(TMRCCR4), located at offset 0x28 from the address in BAR2. The mapping of bits in
this register are as follows:
When this field is read, the current count value is latched and returned. There are
two modes that determine how the count is latched depending on the setting of the
“Read Latch Select” bit in the WDT Control Status Register (CSR2). See the CSR2
register description for more information on these two modes.
Timer 1 IRQ Clear (T1IC)
The Timer 1 IRQ Clear (T1IC) register is used to clear an interrupt caused by Timer 1.
Writing to this register, located at offset 0x30 from the address in BAR2, causes the
interrupt from Timer 1 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.
