MAILBOX DATA LENGTH CONTROL REGIS-
TER (MDLC)
All bits of this register is write protected when the
mailbox is not in empty state.
Read / Write
Reset Value: xxxx xxxx (xxh)
Bit 7 = TGT Transmit Global Time
This bit is active only when the hardware is in the
Time Trigger Communication mode, TTCM bit of
the CCR register is set.
0: MTSRH and MTSRL registers are not sent.
1: MTSRH and MTSRL registers are sent in the
6:4 = Reserved. Forced to 0 by hardware.
Bit 3:0 = DLC[3:0] Data Length Code
This field defines the number of data bytes a data
frame contains or a remote frame request.
