Command ID number: 0x040E
CMD_BUS_REQUEST is an immediate command that takes the parameters listed in Table 26-52.
Byte Index | Field Name | Bits | Bit Field Name | Type | Description |
---|---|---|---|---|---|
0–1 | commandNo | W | The command ID number | ||
2 | bSysBusNeeded | W | 0: System bus may sleep 1: System bus access needed |
On reception, the radio CPU sets the bus request bit toward the PRCM to 1 if bSysBusNeeded is nonzero, or to 0 if bSysBusNeeded is zero. If bSysBusNeeded is nonzero, this indicates that the system bus stays awake even if the system goes to deep sleep, which must be done for the RF core to run and access the system side for one of the following reasons:
CMD_BUS_REQUEST may be sent as a direct command. If so, bSysBusNeeded is given by the parameter in bits 8–15 of CMDR.
The radio CPU returns DONE in CMDSTA when the update finishes.
