1.6.Reset Conditions

The Monaco board responds to three types of reset conditions:

∙VME SYSRESET (VME bus /SYSRESET line)

∙VME A24 Slave Interface Reset (VME A24 Control Register bit D0)

∙JTAG reset (JTAG chain /TRST line)

The following table indicates which hardware components are reset by the specific reset condition.

1.6.1.VME SYSRESET

A VME SYSRESET is initiated when the /SYSRESET line on the VME bus is driven low. All devices and registers on the Monaco board are reset to their default conditions.

1.6.2.VME A24 Slave Interface Reset

The VME A24 slave interface reset is initiated from the VME bus by setting bit D0 of the VME A24 Control Register to “0”. All devices and registers on the Monaco board are reset to their default conditions except for the SCV64 VME interface chip. The VME A24 Control Register is located at VME A24 Base Address + 1004h. The base address for the VME A24 slave interface is set by jumper block JP1.

1.6.3.JTAG Reset

The JTAG path can be reset by asserting the /TRST line of the JTAG chain by an EMURST from the XDS or TBC. Only the JTAG path of the DSPs is reset by this action; no other devices or registers on the board are affected.
