1 Memory
1.1 FAST Memory
RTC FAST Memory 为 8 KB SRAM，其只能被 PRO_CPU 通过数据总线 0x3FF8_0000 ~ 0x3FF8_1FFF 读写，或被 PRO_CPU 通过指令总线 0x400C_0000~0x400C_1FFF 读写。与其他存储器不同，APP_CPU 不能访问 RTC FAST Memory
PRO_CPU 的这两段地址同序访问 RTC FAST Memory。即地址 0x3FF8_0000 与 0x400C_0000 访问到相同的 word，0x3FF8_0004与0x400C_0004访问到相同的word，0x3FF8_0008与0x400C_0008访问到相同的word， 以此类推。APP_CPU 的这两段地址不能访问到 RTC FAST Memory，也不能访问到其他任何目标
1.2 SLOW Memory
RTC SLOW Memory 为 8 KB SRAM，其可以被两个 CPU 通过数据总线与指令总线共用地址段 0x5000_0000 ~ 0x5000_1FFF 读写。

3 Power Consumption
We are care of Deep-Sleep mode:
- The ULP co-porcessor is powered on: 150uA current consumption
- ULP sensor-monitored pattern: 25uA @ 1% duty
- RTC timer + RTC memory: 10uA
And Hibernate Mode:
- The internal 8MHz oscillator and ULP coprocessor are disabled
- The RTC recovery memory are power-down
- Only one RTC timer on the slow clock and some RTC GPIOs are active.
- The RTC timer or the RTC GPIOs can wake up the chip from the Hibernation mode
- Power Consumption: 2.5uA
4 Clock
The RTC clock has five possible sources:
- External low speed (32 KHz) crystal clock
- External crystal clock divided by 4 (40MHz/4 ?)
- Internal RC oscillator (typically about 150 KHz and adjustable)
- Internal 8 MHz oscillator
- Internal 31.25KHz clock (derived from the internal 8MHz oscillator divided by 256)
