7.3 Periodic Mode
: GRA compare match
# Setting example
TSTARTR = 0xC0;
TCONTR4 = 0xA0;
TIER4 = 0xF9;
TCOUNT4 = 0x0000;
GRA4 = 0x0F;
TSTARTR = 0xD0;
7.4 Synchronizing Mode
: In a periodic mode counter cleared by GRA of channel0
In a periodic mode counter cleared by GRB of channel1
In a periodic mode counter cleared, synchronized with other sync. timer (channel2, 3, 4, 5)
Toggle output at GRA of channel0, 2, 4
Toggle output at GRB of channel1, 3, 5
# Setting example
