Web10. The PWM 1:6 Value Registers (PVAL1H:L, PVAL6H:L) – Holds a 16-bit signed value that determines the duty cycle of the PWM 11. The Dead-Time Write-Once Register (DEADTM) which: – Holds an 8-bit value that determines the number of PWM cycles to turn off the PWM pairs when configured in complementary fashion 12. WebBTW: the first sketch reads value in POTD register, not the value on the actual pin. It might be for example shorted and PIND register would read it correctly. It's possible to read the actual value (by reading PIND) but as Majenko wrote, it's changing, so you'd have to read it at constant rate or measure the low and high time. modmiss shoes
