19 controller contains 4 sub-modules, i.e. EIC-debounce, EIC-latch, EIC-async and
20 EIC-sync. But the PMIC EIC controller contains only one EIC-debounce sub-
23 The EIC-debounce sub-module provides up to 8 source input signal
24 connections. A debounce mechanism is used to capture the input signals'
25 stable status (millisecond resolution) and a single-trigger mechanism
26 is introduced into this sub-module to enhance the input event detection
27 reliability. In addition, this sub-module's clock can be shut off
28 automatically to reduce power dissipation. Moreover the debounce range
29 is from 1ms to 4s with a step size of 1ms. The input signal will be
30 ignored if it is asserted for less than 1 ms.
32 The EIC-latch sub-module is used to latch some special power down signals
33 and generate interrupts, since the EIC-latch does not depend on the APB
36 The EIC-async sub-module uses a 32kHz clock to capture the short signals
39 The EIC-sync is similar with GPIO's input function, which is a synchronized
