RELIANCE 45C322電源模塊
時(shí)間報警寄存器以與時(shí)間寄存器相同的格式讀取和寫(xiě)入。時(shí)間監視器報警寄存器寄存器C包含兩個(gè)監視器報警值。位3-0包含0.01秒值，BCD格式的范圍為0到9，而位7-4包含0.1秒值，以BCD格式，范圍為0至9。此寄存器的總范圍為0.00至0.99秒。寄存器D包含兩個(gè)看門(mén)狗報警值。位3-0包含1秒值，BCD格式范圍為0到9，而位7-4包含10秒值，十進(jìn)制范圍為0至9。此寄存器的總范圍為00.0到99.0秒?？撮T(mén)狗報警寄存器可以按任何順序讀取或寫(xiě)入。當輸入新值或讀取看門(mén)狗寄存器時(shí)，看門(mén)狗定時(shí)器將從輸入值開(kāi)始倒數。當達到零時(shí)，看門(mén)狗中斷輸出將激活。如果跳線(xiàn)J30已加載，CPU將重置為已知狀態(tài)。
The Time of Day Alarm registers are read and written to in the same format as the Time of Day registers. The Time of Day Watchdog Alarm Registers Register C contains two Watchdog Alarm values. Bits 3 - 0 contain the 0.01 Seconds value with a range of 0 to 9 in BCD, while Bits 7 - 4 contain the 0.1 Seconds value with a range of 0 to 9 in BCD. This Register has a total range of 0.00 to 0.99 Seconds. Register D contains two Watchdog Alarm values. Bits 3 - 0 contain the 1 Second value with a range of 0 to 9 in BCD, while Bits 7 - 4 contain the 10 Seconds value with a range of 0 to 9 in BCD. This register has a total range of 00.0 to 99.0 Seconds. The Watchdog Alarm Registers can be read or written in any order. When a new value is entered or the Watchdog registers are read, the Watchdog Timer will start counting down from the entered value. When zero is reached the Watchdog Interrupt Output will go active. If jumper J30 is loaded, the CPU will reset to a known state.
