XMEGA A
• Bit 3 - SPI: Serial Peripheral Interface
Setting this bit stops the clock to the SPI. When the bit is cleared the peripheral should be reini-
tialized to ensure proper operation.
• Bit 2 - HIRES: Hi-Resolution Extension
Setting this bit stops the clock to the Hi-Resolution Extension for the Timer/Counters. When the
bit is cleared the peripheral should be reinitialized to ensure proper operation.
• Bit 1 - TC1: Timer/Counter 1
Setting this bit stops the clock to the Timer/Counter 1. When the bit is cleared the peripheral will
continue like before the shut down.
• Bit 0 - TC0: Timer/Counter 0
Setting this bit stops the clock to the Timer/Counter 0. When the bit is cleared the peripheral will
continue like before the shut down.
