DS_1210F_001  
Keypad Column Register (KCOL): 0xD1 0x1F  
This register contains the value of the column of a key detected as valid by the hardware. In bypass  
mode, this register firmware writes directly this register to carry out manual scanning.

Drive lines bit mapped to corresponding with pins COL(4:0). When a key  
is detected, firmware reads this register to determine column. In bypass  
(S/W keyscan) mode, Firmware writes this register directly. 0x1E =  
COL(0) low, all others high. 0x0F = COL(4) low, all others high. 0x1F =  
COL(4:0) all high.  
Keypad Row Register (KROW): 0xD2 0x3F  
This register contains the value of the row of a key detected as valid by the hardware. In bypass mode,  
this register firmware reads directly this register to carry out manual detection.

Sense lines bit mapped to correspond with pins ROW(5:0). When key  
detected, firmware reads this register to determine row. In bypass mode,  
firmware reads rows and has to determine if there was a key press or not.  
0x3E = ROW(0) low, all others high. 0x1F = ROW(5) low, all others high.  
0x3F = ROW(5:0) all high.
