DB9
Data Output Bit 9
Note 1: INSEL=0 —> SCLK, SDI, and LOAD pins are active for serial programming; INSEL=1 —> SCLK and SDI pins
are inactive, and the serial programming is done through I/O pins DB12 and DB13 as described in Notes 3~4 with
LOAD tri-stating DB12 and DB13.
Note 2: OUTSEL=0 —> 14-bit parallel output mode select; OUTSEL=1 —> 8-bit nibble output mode select.
Note 3: For INSEL=1, DB12 becomes the SCLK input during serial programming.
Note 4: For INSEL=1, DB13 becomes the SDI input during serial programming.
Note 5: Pins 17, 20 and 23 may be connected to AGND2 to improve noise immunity.
