8-Bit Micro-controller
64KB with ISP Flash
& 6K+256B RAM embedded
1000_0000 means 128 successive “1”
[ ※Greater than 128 will continue to increase])
11 = Enable barcode decoder. [Decode the 8 bits of ADC data (MSB)]
Analysis/count barcode raw data then write the results into SRAM.
The results data format as following:
b7 : convert data
b[6:0]: length
ex: 1000_0111 means 7 successive “1”.
1000_1000 means 8 successive “1”.
1000_0000 means greater then 128 successive “1”
[※Will not increase more than 128] )
BarcodeINF[1:0] Barcode Input Noise Filter
00 = 1 consecutive same value recognize as valid data.
01 = 2 consecutive same value recognize as valid data.
10 = 3 consecutive same value recognize as valid data.
11 = 4 consecutive same value recognize as valid data.
RAWBITNUM Raw Data Bit Number
0 = 10 bit; HW write raw data 10 bit into SRAM.
1 = 8 bit; HW write raw data 8 bit (MSB) into SRAM.
ADCDS The ADC of data select
[1:0] 00 = Compared with the previous first ADC of data.
01 = Compared with the previous second ADC of data.
10 = Compared with the previous third ADC of data.
11 = Compared with the previous fourth ADC of data.
bcdidv Initial digital value of Barcode decoder
bcdidv = 1 after system reset
