36.2.68 Transmit Buffer Register pAH (TMIDHp) (p = 0 to 3)
Modify this register when the corresponding TMSTSp.TMTRM flag is 0 (no transmit request is present). If this register
is linked to any transmit/receive FIFO buffer, do not write data to this register.
This register can be read/written when the GRWCR.RPAGE bit is 1.
TMID[28:16] Bits (Transmit Buffer ID Data H)
These bits are used to set the ID of the message to be transmitted from the transmit buffer.
THLEN Bit (Transmit History Data Store Enable)
When this bit is set to 1, the transmit history data (label information, buffer number, and buffer type) of transmit
messages is stored in the transmit history buffer after transmission is completed.
TMRTR Bit (Transmit Buffer RTR)
This bit is used to set the data format of the message to be transmitted from the transmit buffer.
TMIDE Bit (Transmit Buffer IDE)
This bit is used to set the ID format of the message to be transmitted from the transmit buffer.
