Table 22-15. POCR Field Descriptions
Field
Description
WME
Write Mode External Correction — This bit controls the write mode of the EOC_AP and ERC_AP fields.
0 Write to EOC_AP and ERC_AP fields on register write.
1 No write to EOC_AP and ERC_AP fields on register write.
EOC_AP
External Offset Correction Application — This field is used to trigger the application of the external offset
correction value defined in the Protocol Configuration Register 29 (PCR29).
00 do not apply external offset correction value
01 reserved
10 subtract external offset correction value
11 add external offset correction value
ERC_AP
External Rate Correction Application — This field is used to trigger application of the external rate correction
value defined in the Protocol Configuration Register 21 (PCR21)
00 do not apply external rate correction value
01 reserved
10 subtract external rate correction value
11 add external rate correction value
BSY
WMC
Protocol Control Command Write Busy — This status bit indicates the acceptance of the protocol control
command issued by the application via the POCCMD field. The controller sets this status bit when the application
has issued a protocol control command via the POCCMD field. The controller clears this status bit when protocol
control command was accepted by the PE.When the application issues a protocol control command while the
BSY bit is asserted, the controller ignores this command, sets the protocol command ignored error flag
PCMI_EF in the CHI Error Flag Register (CHIERFR), and will not change the value of the POCCMD field.
0 Command write idle, command accepted and ready to receive new protocol command.
1 Command write busy, command not yet accepted, not ready to receive new protocol command.
Write Mode Command — This bit controls the write mode of the POCCMD field.
0 Write to POCCMD field on register write.
1 Do not write to POCCMD field on register write.
POCCMD
Protocol Control Command — The application writes to this field to issue a protocol control command to the
PE. The controller sends the protocol command to the PE immediately. While the transfer is running, the BSY
bit is set.
0000 ALLOW_COLDSTART — Immediately activate capability of node to cold start cluster.
0001 ALL_SLOTS — Delayed¹ transition to the all slots transmission mode.
0010 CONFIG — Immediately transition to the POC:config state.
0011 FREEZE — Immediately transition to the POC:halt state.
0100 READY, CONFIG_COMPLETE — Immediately transition to the POC:ready state.
0101 RUN — Immediately transition to the POC:startup start state.
0110 DEFAULT_CONFIG — Immediately transition to the POC:default config state.
0111 HALT — Delayed transition to the POC:halt state
1000 WAKEUP — Immediately initiate the wakeup procedure.
