MCP19111

CONFIGURING THE MCP19111

The MCP19111 is an analog controller with digital

peripheral. This means that device configuration is

handled through register settings instead of adding

external components. The following sections detail how

to set the analog control registers.

6.1

Input Under Voltage Lockout

The VINLVL register contains the digital value that sets

the input under voltage lockout. When the input voltage

on the VIN pin to the MCP19111 is below this pro-

grammed level, the INTCON<VINIF> flag will be set.

This bit is automatically cleared when the MCP19111

VIN voltage rises above this programmed level.

The VINLVL<UVLOEN> bit must be set to enable the

input under voltage lockout circuitry.

Note:

The VINIF interrupt flag bit is set when an

interrupt condition occurs, regardless of

the state of its corresponding enable bit or

the Global Enable bit, GIE, of the INTCON
