23.2.27
Timer Buffer Transfer Set Registers (TBTER)
The TBTER registers enable or disable transfer from the buffer registers used in complementary PWM mode to the
temporary registers and specify whether to link the transfer with interrupt skipping operation.
Note:
Target buffer registers: MTU3.TGRC, MTU3.TGRD, MTU4.TGRC, MTU4.TGRD, and MTU.TCBR
Note 1. Data is transferred in accordance with the TMDR.MD[3:0] bit setting. For details, refer to section 23.3.8, Complementary PWM
Note 2. When interrupt skipping is disabled (the TITCR.T3AEN and T4VEN bits or the interrupt skipping count setting bits (T3ACOR[2:0]
and T4VCOR[2:0]) in the TITCR register are set to 000b), be sure to disable link of buffer transfer with interrupt skipping (set the
TBTER.BTE[1] bit to 0).
If link with interrupt skipping is enabled while interrupt skipping is disabled, buffer transfer will not be performed.
