BODEN: BOD function control 1 1: BOD function disabled; 0: BOD function enabled
BODLEVEL: BOD level selection 1 1: 2.7V level; 0: 4.0V level
BOOTRST: Reset entry selection 1 1: The program starts to execute from the address 0x0000; 0: The program starts to execute from the entry address determined by the boot area
**********************************
BOOTSZ1/0: Boot area program size and entry 00        
00: 1024Word/0xc00;
01: 512Word/0xe00;
10: 256Word/0xf00;
11: 128Word/0xf80
********************************
BLB02/01: Program area instruction bit selection 11
11: Both SPM and LPM instructions are allowed to execute
10: SPM instruction prohibits writing to the program area
01: Boot area LPM instruction prohibits reading the program area content; if the interrupt vector is defined in the boot area, the interrupt is prohibited from executing in the program area.
00: SPM instruction prohibits writing to the program area; Boot area LPM instruction prohibits reading the program area content; if the interrupt vector is defined in the boot area, the interrupt is prohibited from executing in the program area.
********************************
BLB12/11: Boot sector instruction bit selection 11
11: Both SPM and LPM instructions are allowed to execute
10: SPM instruction prohibits writing boot sector
01: Program area LPM instruction prohibits reading boot sector content; if the interrupt vector is defined in the program area, the interrupt is prohibited from executing in the boot sector.
00: SPM instruction prohibits writing boot sector; program area LPM instruction prohibits reading boot sector content; if the interrupt vector is defined in the program area, the interrupt is prohibited from executing in the boot sector.
********************************
LB2/1: Program area encryption bit selection 11        
11: Unencrypted
10: Program and EEPROM programming function disabled, fuse bit locked
00: Program and EEPROM programming and verification function disabled, fuse bit locked
(Note: program other fuse bits first, then program the encryption bit)
********************************
CKSEL3/0: Clock source selection 0001
CKOPT: Crystal oscillator selection 1
SUT1/0: Reset start time selection 10
********************************
CKSEL3/0＝0000: External clock, CKOPT＝0: Allow the chip's internal XTAL1 pin to connect a 36PF capacitor to GND; CKOPT＝1: Disable the capacitor
----------------
CKSEL3/0＝0001-0100: Calibrated internal RC oscillator, CKOPT is always 1
0001: 1.0M
0010: 2.0M
0011: 4.0M
0100: 8.0M
----------------
CKSEL3/0=0101-1000: External RC oscillation, CKOPT=0: Allow the chip's internal XTAL1 pin to connect a 36PF capacitor to GND; CKOPT=1: Disable this capacitor
0101: <0.9M
0110: 0.9-3.0M
0111: 3.0-8.0M
1000: 8.0-12.0M
----------------
CKSEL3/0=1001: External low-frequency crystal oscillator, CKOPT=0: Allow the chip's internal XTAL1/XTAL2 pins to connect a 36PF capacitor to GND; CKOPT=1: Disable this capacitor
----------------
CKSEL3/0=1010-1111: External crystal oscillator, ceramic resonator, CKOPT=0: High amplitude oscillation output; CKOPT=1: Low amplitude oscillation output
101X: 0.4-0.9M
110X: 0.9-3.0M
111X: 3.0-8.0M
********************************
SUT1/0: Reset start time selection
When different crystal oscillators are selected, the SUT is different.
