Table 26-16. FR_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 (FR_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 (FR_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 CC sets this status
bit when the application has issued a protocol control command via the POCCMD field. The CC
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 CC ignores this
command, sets the protocol command ignored error flag PCMI_EF in the CHI Error Flag Register
(FR_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 CC 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.
