9.3.25
TCBR is a 16-bit register used only in complementary PWM mode. It functions as a buffer
register for the TCDR register. The TCBR register values are transferred to the TCDR register
with the transfer timing set in the TMDR register.
The initial value of TCBR is H'FFFF.
Initial value:
9.3.26
TITCR is an 8-bit readable/writable register that enables or disables interrupt skipping and
specifies the interrupt skipping count. The MTU2 has one TITCR.
