Transmit message buffers:
This bit is not used.
3.3.2.10 STARTUP — Startup Bit
The STARTUP bit determines whether the frame is to be used for clock synchronization during startup.
Receive message buffers and Receive FIFO
The bit contains the STARTUP bit of the stored frame. This bit is updated only when a new semantically
valid frame matching the buffer filters has been stored in the message buffer.
Transmit message buffers
This bit is not used.
3.3.3
All message buffers, including transmit buffers, comprise a message buffer slot status vector holding a
9-bit wide slot status information field.

Message Buffer Slot Status Vector
The host sets up the slot ID determining the slot during which the CC
transmits a sync frame via the sync frame register SYNCFR (see
Section 3.2.3.3.29, “Sync Frame Register
The host sets up the STARTUP bit for transmit frames via the startup bit
SUP in register SYNCFR (see
(SYNCFR)”).
