AT43USB325
from an interrupt, it will always return to the main program and execute one more instruction
before any pending interrupt is served.
4.11.1
MCU Control Register – MCUCR
Bit 7, 6 – Res: Reserved Bits
Bit 5 – SE: Sleep Enable
The SE bit must be set (1) to make the MCU enter the sleep mode when the SLEEP instruction
is executed. To avoid the MCU entering the sleep mode, unless it is the programmer's purpose,
it is recommended to set the Sleep Enable SE bit just before the execution of the SLEEP
instruction.
Bit 4 – SM: Sleep Mode
This bit selects between the two available sleep modes. When SM is cleared (zero), Idle Mode is
selected as Sleep Mode. When SM is set (1), Power Down mode is selected as sleep mode. The
AT43USB325 does not support the Idle Mode and SM should always be set to one when enter-
ing the Sleep Mode.
Bit 3, 2 – ISC11, ISC10: Interrupt Sense Control 1 Bit 1 and Bit 0
The External Interrupt 1 is activated by the external pin INT1 if the SREG I-flag and the corre-
sponding interrupt mask in the GIMSK is set. The level and edges on the external INT1 pin that
activate the interrupt are defined in the following table:
