A non-15.4 radio operation may not be run simultaneously with a 15.4 radio operation; if a non-15.4 radio
operation is entered while a 15.4 operation is running on either level, scheduling error occurs. Chains of
15.4 and non-15.4 operations can be created, however.
When a foreground-level operation finishes, an FG_COMMAND_DONE interrupt is raised. If the command
was the last one in a chain, a LAST_FG_COMMAND_DONE interrupt is raised as well (refer to
Table 23-77). Background-level operations use the common interrupts, COMMAND_DONE and
LAST_COMMAND_DONE (see
The status field of the command structure is updated during the operation. When submitting the
command, the system CPU writes this field with a state of IDLE. During the operation, the radio CPU
updates the field to indicate the operation mode. When the operation is done, the radio CPU writes a
status indicating that the command has finished. The status codes for IEEE 802.15.4 radio operation are
listed in Table 23-79.
