【Note】
1.
Rewrite the enable/disable of the transmit history buffer (the THLE bit of the THLCCm register) in
channel communication mode or channel standby mode.
2.
Even if the use of the transmit history buffer is prohibited (the THLE bit is “0”) while an interrupt request is
generated (the THLIF flag in the THLSTSm register is “1”), the interrupt request flag (the THLIF flag) is not
automatically set to “0”. Set the interrupt request flag to "0" with the program.
