Configures channel A or B of the live probe system. A live probe is enabled by writing a local address register within one of the probe segment modules. Each probe segment module generates its own local channel A live probe outputs. The live probe outputs are combined to generate a chip-level live probe channel A signal.
The local live probe may be used internally within the user design or the global channel output may be sent to an IO. To support these options, an option is provided which clears all local channel configurations before configuring a new one.
When configuring channel A, channel B is not affected and vice-versa.
System Service Descriptor Bit Field | Value | Description |
---|---|---|
15:7 | MBOXADDR[10:2] | Mailbox address. See Table 2. |
6:0 | 72H | Live Probe Channel A service command |
73H | Live Probe Channel B service command |
The following table lists the Live Probe Service mailbox format.
Offset (Byte) | Offset (Bit) | Length (Bits) | Parameter | Direction | Description |
---|---|---|---|---|---|
0 | 0 | 5 | XADDR[4:0] | Input | Specifies the X co-ordinate within target probe module. |
0 | 5 | 6 | YADDR[5:0] | Input | Specifies the Y co-ordinate within target probe module. |
2 | 0 | 6 | IPSEGADDR[5:0] | Input | Specifies the probe segment address and the target address of probe module. |
2 | 6 | 5 | IPROWADDR[4:0] | Input | Specifies the probe row address and the target address of probe module. |
4 | 0 | 1 | CLEAR | Input | Clears the configurations of local channels A or B. If CLEAR is ‘1’, all local channel x (the applicable channel A or B) configurations are cleared before applying the new configuration. |
5 | 0 | 1 | IOEN | Input | Activates the probe output pad. If IOEN is ‘1’, the corresponding live probe output pad is activated. Note that setting IOEN to ‘0’ does not disable the internal live probe configuration. |
