4.5.2 STATUS_REQ Structure

Structure used to indicate the state of the MPC18x as well as the driver. Returned as a pointer by

GetStatus() and imbedded in all requests. Each element is a copy of the contents of the same register in

the MCP18x driver. This structure is also known as

MPC18x_STATUS through a typedef.
