Register Description
ATtiny4/5/9/10
CCP – Configuration Change Protection Register
SPH and SPL — Stack Pointer Register
SREG – Status Register
• Bits 7:0 – CCP[7:0] – Configuration Change Protection
In order to change the contents of a protected I/O register the CCP register must first be written
with the correct signature. After CCP is written the protected I/O registers may be written to dur-
ing the next four CPU instruction cycles. All interrupts are ignored during these cycles. After
these cycles interrupts are automatically handled again by the CPU, and any pending interrupts
will be executed according to their priority.
When the protected I/O register signature is written, CCP[0] will read as one as long as the pro-
tected feature is enabled, while CCP[7:1] will always read as zero.
Table 4-1
Table 4-1.
• Bit 7 – I: Global Interrupt Enable
The Global Interrupt Enable bit must be set for the interrupts to be enabled. The individual inter-
rupt enable control is then performed in separate control registers. If the Global Interrupt Enable
Register is cleared, none of the interrupts are enabled independent of the individual interrupt
enable settings. The I-bit is cleared by hardware after an interrupt has occurred, and is set by
the RETI instruction to enable subsequent interrupts. The I-bit can also be set and cleared by
the application with the SEI and CLI instructions, as described in the document “AVR Instruction
Set” and
