EPSON RX8010SJ RTC 调试笔记之四， 报警中断功能 (Alarm Interrupt Function)

硬件: EPSON RX8010 SJ

功能描述:

报警中断功能 (Alarm Interrupt Function) 分日期或周两种报警模式，于设定时间（小时和分钟）产生中断事件。

当报警中断事件产生时，AF 标志位会被置 "1", 引脚 IRQ1 电平被置低为 "0" . 当报警中断触发后的 1.46mS (最大时间), AF 标志位和 IRQ1 输出状态会被改变. 

IRQ1="L" 会保持，除非给予强制中止指令

** 清除标志寄存器 FLAG Register 的标志位 AF 为 "0", IRQ1 输出则会为返回高电平或 Hi-Z 状态. 

报警中断具体功能：

1. 周模式;  <扩展寄存器 Extension Register 标志位 WADA="0">
    1.1 一周中每天指定 hh:mm 时间产生报警中断;
    1.2 一周中某天或某几天, 于 hh:?? 时间产生小时整点报警; (分钟设定被忽略)
    1.3 一周中某天或某几天, 于每个小时的 ??:mm 时间产生报警; (小时设定被忽略)

2. 日期模式;  <扩展寄存器 Extension Register 标志位 WADA="1">
    2.1 每天指定 hh:mm 时间产生报警中断;
    2.2 于某天 hh:?? 时间产生小时整点报警; (分钟设定被忽略)
    2.3 于某天每个小时的 ??:mm 时间产生报警; (小时设定被忽略)

设定报警中断功能流程

功能图

?! IRQ1 中断触发后，AF bit 复位为 "0" 时, 程序中 IRQ1 低电平中断再次触发一次, 须特别注意，目前尚未找到原因; ?? IRQ1 为 Hi-Z 输出信号造成?
