Reset of One microcontroller using the other (Msp430)

Other Parts Discussed in Thread: MSP430F1611

Hey guys i'm having a bit of a problem executing my program.

I generated a reset outmod using timer A in a MSP430f1611 microcontroller, and i wanted to pass this signal to another microcontroller to hold it on an off state for however long i want. 

I just want to know if there is any special configuration of the RST/NMI pin, and if there is, in which register the configuration is to be done. 

Cheers

    The RST/NMI pin must be tied to VCC for proper functionallity. Its like a switch

    Check the datasheet (POR/Brownout Reset characterists).

    Hope this help you

    There ar esome configuration options for the RST pin, but the default is the one you need for using it as reset anyway.

    As logn as teh RST pin is low, the MSP is stopped. The CPU is topped, and much of the internal hardware is reset. Once RST goes high, teh rest of the internal hardware will be initialized as well as teh CPU that starts running.
    However, RST state is not OFF state. Manually configuring the MSP for OFF (with RST high, but the MSP shut down in LPM4 or even LPM4.5) will result is a much lesser power consumption. The MSP can then be awakened by a short low pulse on RST.

    Alternatively (if the peripheral connections allow this), just shut off its power supply (e.g. by a FET).
