Modes of Operation
4.1
Introduction
The operating modes of the MPR083 are described in this section. Implementation and functionality of each mode are described.
The Modes of Operation of the MPR083 combine to form a suite of quick response and low power consumption functionality. This
is achieved through 2 Run modes and 2 Stop Modes. The two modes are enabled by toggling the Configuration Register’s DCE
and RUNE bits as shown in Table 7. Note that while in a run mode, the only register that can be written to is the Configuration
Register. Thus, when changes to registers are needed, enter Stop1 mode, write to the registers and change the mode to “Run”.
4.2
Initial Power Up
On power-up, the interrupt output IRQ is reset, and IRQ will go high. The registers are reset to the values shown in Table 8.
