5.3.4 Board Control Registers

The board control register is used to generate a local reset to the CC121 board, and to control the interrupt output.

Figure 5-3 Board Control Register

EBI

Enable Board Interrupt - If this bit is set, the interrupt output to the VMEbus is enabled. After reset this bit is cleared, which disables the interrupt output.

RES

Reset - This bit is used to reset the COM9026 by writing a '1' followed by a '0'. The time between the two consecutive write cycles determines the reset time and must be at least 2 µs. This bit is cleared after a VMEbus reset.
