VD latch H12_Buff
MON
• MON (D0 to D2 of address H’F4)
Select the pulse which output to pin MON (pin 60).
When D0 to D2: 0, Fix to Low
When 1, ADCLK
When 2, SP1
When 3, SP2
When 4, OBP
When 5, PBLK
When 6, CPDM
When 7, DLL_test
• H12Baff (D3 to D6 of address H’F4)
Select the buffer size which output to pin H1A, H2A (pin 22, 26).
D3: 2 mA buffer
D4: 4 mA buffer
D5: 10 mA buffer
D6: 14 mA buffer
Above data can be on/off individually. Default is D6 can be on only. (18 mA buffer)
• VD latch (D7 of address H’F4)
Data = 0: Gain data is determined when CS rising
Data = 1: Gain data is determined when VD falling
Gray_test Gray code
