Section 13 Timer Z
Figures 13.42 and 13.43 show the operation examples when buffer operation has been designated
for GRB_0 and GRD_0 in complementary PWM mode. These are examples when a PWM
waveform of 0% duty is created by using the buffer operation and performing GRD_0 ≥ GRA_0.
Data is transferred from GRD_0 to GRB_0 according to the settings of CMD_0 and CMD_1 when
TCNT_0 and GRA_0 are compared and their contents match or when TCNT_1 underflows.
However, when GRD_0 ≥ GRA_0, data is transferred from GRD_0 to GRB_0 when TCNT_1
underflows regardless of the setting of CMD_0 and CMD_1. When GRD_0 = H'0000, data is
transferred from GRD_0 to GRB_0 when TCNT_0 and GRA_0 are compared and their contents
match regardless of the settings of CMD_0 and CMD_1.
