Description
Lock Status Indication
Set to 1 when a unit is locked by a lock request from the
master unit. IELA1 and IELA2 values are valid only when
this flag is set to 1.
1: A unit is locked
[Setting condition]
•
0: A unit is unlocked
[Clearing condition]
•
Reserved
This bit is always read as 0.
Receive Broadcast Bit Status
Indicates the received broadcast bit value. This flag is valid
when the slave/broadcast reception is started. (This flag is
changed at the timing of setting the RxS flag in IERSR.)
The previous value remains unchanged until the next
slave/broadcast reception is started.
When data for the number of bytes specified by the
message length is not received after the control bits
that make the unit locked are received from the master
unit. (The LCK flag is set to 1 only when the message
length exceeds the maximum number of transfer bytes
in one frame. This flag is not set by completion of other
errors.)
When an unlock condition is satisfied or when an
unlock command is issued.
