Register Description
Register Summary
CTRLA - Hi-Res Control Register A
Name
CTRLA
• Bit 7:2 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 1:0 - HREN[1:0]: Hi-Resolution Enable
Enables Hi-Resolution mode for a Timer/Counter according to
Setting one or both HREN bits will enable Hi-Resolution waveform generation output for the
entire general purpose I/O port. This means that both Timer/Counters connected to the same
port must enable Hi-Res if both are used for generating PWM or FRQ output on pins.
