TCR is an 8-bit readable/writable register that selects the clock input to TCNT and controls PWM  
output.  
TCR is initialized to H'38 by a reset and in standby mode.  
Bit 7—Output Enable (OE): This bit enables the timer counter and the PWM output.  
Bit 7: OE  
Description  
0
1
PWM output is disabled. TCNT is cleared to H'00 and stopped.  
PWM output is enabled. TCNT runs.  
(Initial value)  
Bit 6—Output Select (OS): This bit selects positive or negative logic for the PWM output.  
Bit 6: OS  
Description  
0

Positive logic; positive-going PWM pulse, 1 = high  
Negative logic; negative-going PWM pulse, 1 = low  
(Initial value)  
Bits 5 to 3—Reserved: These bits cannot be modified and are always read as 1.
