Notes

1.RESET switch control.

2.Watchdog timer control.

3.Access and watchdog timer parameters.

4.MPU TEA (bus error) status

5.Bit numbering for the VMEchip2 and Petra ASICs has a one-to-one correspondence.

6.ABORT switch interrupt control. Implemented also in the VMEchip2, but with a different bit organization (refer to the VMEchip2 description in Chapter 2). In the MVME1X7P, the ABORT switch is wired to the Petra chip, not the VMEchip2.

7.The SRAM and EPROM decoder in the VMEchip2 (version 2) must be disabled by software before any accesses are made to these address spaces.
