Atmel AVR XMEGA AU
15.10.10 HCNT – High-byte Count register
• Bit 7:0 – HCNT[7:0]
HCNT contains the eight-bit counter value for the high-byte timer/counter. The CPU and DMA
write accesses have priority over count, clear, or reload of the counter.
15.10.11 LPER – Low-byte Period register
• Bit 7:0 – LPER[7:0]
LPER contains the eight-bit period value for the low-byte timer/counter.
15.10.12 HPER – High-byte Period register
• Bit 7:0 – HPER[7:0]
HPER contains the eight-bit period for the high-byte timer/counter.
15.10.13 LCMPx – Low-byte Compare register x
• Bit 7:0 – LCMPx[7:0], x=[A, B, C, D]
LCMPx contains the eight-bit compare value for the low-byte timer/counter.
These registers are all continuously compared to the counter value. Normally, the outputs from
the comparators are then used for generating waveforms.
