Block is not scheduled and
therefore cannot execute to
go to Target Mode.
Typically, BLOCK_ERR [6]
will show "Power-Up" for all
blocks that are not
scheduled. Schedule the
block to execute.
FEATURES_SEL [18] in
the resource block does
not have Alerts enabled.
Enable the Alerts bit.
LIM_NOTIFY [32] in the
resource block is not high
enough. Set equal to
MAX_NOTIFY [31], also in
the resource block.
