Register Description
ATtiny4/5/9/10
NVMCSR - Non-Volatile Memory Control and Status Register
NVMCMD - Non-Volatile Memory Command Register
• Bit 7 - NVMBSY: Non-Volatile Memory Busy
This bit indicates the NVM memory (Flash memory and Lock Bits) is busy, being programmed.
This bit is set when a program operation is started, and it remains set until the operation has
been completed.
• Bit 6:0 - Res: Reserved Bits
These bits are reserved and will always be read as zero.
• Bit 7:6 - Res: Reserved Bits
These bits are reserved and will always read zero.
• Bit 5:0 - NVMCMD[5:0]: Non-Volatile Memory Command
These bits define the programming commands for the flash, as shown in
Table 15-10. NVM Programming commands
