Timer Cycle Data Register (TCDR)

TCDR is a 16-bit register used only in complementary PWM mode. Set half the PWM carrier cycle value (however, the
value must also be at least twice the setting of TDDR plus 3) as the TCDR register value. This register is constantly
compared with the TCNTS counter in complementary PWM mode, and when a match occurs, the TCNTS counter
switches direction (decrement to increment).
The initial value of TCDR is H'FFFF.
Bit: 15
Initial value: 1
R/W: R/W
Note: Accessing the TCDR in 8-bit units is prohibited. Always access in 16-bit units.
10.3.24

Timer Cycle Buffer Register (TCBR)

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.
Bit: 15
Initial value: 1
R/W: R/W
Note: Accessing the TCBR in 8-bit units is prohibited. Always access in 16-bit units.
