6-phase output

When BCD = 1, N = 1, P = 1, FB = 1, output active level = high

A/D Conversion Start Request Setting: In complementary PWM mode, an A/D conversion start
request can be set using a TGRA_3 compare-match or a compare-match on a channel other than
channels 3 and 4.

When start requests using a TGRA_3 compare-match are set, A/D conversion can be started at the
center of the PWM pulse.

A/D conversion start requests can be set by setting the TTGE bit to 1 in the timer interrupt enable
register (TIER).

Complementary PWM Mode Output Protection Function

Complementary PWM mode output has the following protection functions.

Register and Counter Miswrite Prevention Function: With the exception of the buffer
registers, which can be rewritten at any time, access by the CPU can be enabled or disabled for the
mode registers, control registers, compare registers, and counters used in complementary PWM
mode by means of bit 0 (MTURWE) in PEMTURWER of the port E (port E MTU R/W enable
register).
