MV64360 System Controller

Functional Description

 

 

4.3.4.14 Board Reset Logic

The board reset logic is implemented in a programmable logic device (PLD) in order to provide maximum flexibility of the circuit. Refer to Sources of Reset on page 86 for a summary of potential reset sources.

4.3.4.15 MV64360 MPP Configuration

The MV64360 contains a 32-bit multi-purpose port (MPP). The MPP pins can be configured as general purpose I/O pins, as external interrupt inputs, or as specific control/status pins for one of the MV64360 internal devices. After reset, all MPP pins default to general purpose inputs. Software must then configure each of the pins for the desired function. The following table defines the function assigned to each MPP pin on the CPCI-6115 board.
