23.5.16 Amplitude Register
The TCEn.AMPL and TCEn.AMPH register pair represents the 16-bit value, TCEn.AMP. The low byte [7:0] (suffix L) is accessible at the
original offset. The high byte [15:8] (suffix H) can be accessed at offset +
0x01. CPU and UPDI write access has priority over internal updates of the register.
The TCEn.AMP register holds the 16-bit value used to set the range for the compare
registers and the min/max PWM duty cycle. When SCALE and AMPEN in TCEn.CTRLD are
enabled, the min/max duty cycle is limited to the range defined by the AMP and
OFFSET registers. The AMP register is not in use if AMPEN =
‘0’.
