Bit Name Value R/W Description
5
BFB
0
R/W Buffer Operation B
Specifies whether TGRB is to operate in the normal
way, or TGRB and TGRD are to be used together for
buffer operation. When TGRD is used as a buffer
register, TGRD input capture/output compare do not
take place in modes other than complementary PWM
mode, but compare match with TGRD occurs in
complementary PWM mode. Since the TGFD flag will
be set if a compare match occurs during Tb interval in
complementary PWM mode, the TGIED bit in timer
interrupt enable register 3/4 (TIER_3/4) should be
cleared to 0.
In channels 1 and 2, which have no TGRD, bit 5 is
reserved. It is always read as 0 and cannot be modified.
0: TGRB and TGRD operate normally
1: TGRB and TGRD used together for buffer operation

R/W Buffer Operation A
Specifies whether TGRA is to operate in the normal
way, or TGRA and TGRC are to be used together for
buffer operation. When TGRC is used as a buffer
register, TGRC input capture/output compare do not
take place in modes other than complementary PWM
mode, but compare match with TGRC occurs in
complementary PWM mode. Since the TGFC flag will
be set if a compare match occurs on channel 4 during
Tb interval in complementary PWM mode, the TGIEC
bit in timer interrupt enable register 4 (TIER_4) should
be cleared to 0.
In channels 1 and 2, which have no TGRC, bit 4 is
reserved. It is always read as 0 and cannot be modified.
0: TGRA and TGRC operate normally
1: TGRA and TGRC used together for buffer operation
3 to 0 MD[3:0]

R/W Modes 0 to 3
These bits are used to set the timer operating mode.
