CTRLE - Control Register E
INTCTRLA - Interrupt Enable Register A
Table 14-6.
• Bit 7:1 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 0 - BYTEM: Byte Mode:
Enabling the Byte Mode, sets the Timer/Counter in Byte (8-bit) Mode. Setting this bit will disable
the update of the temporary register (TEMP) when any of the 16-bit Timer/Counter registers are
accessed. In addition the upper byte of the counter (CNT) register will be set to zero after each
counter clock.
• Bit 7:4 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
