Keypad Scan Time Register (KSIZE): 0xD5
0x00
This register is not applicable when HWSCEN is not set. Unused row inputs should be connected to
VDD.

Defines the number of rows in the keypad. Maximum number is 6 given
the number of row pins on the package. Allows for a reduced keypad size
for scanning.

Keypad Column LS Scan Order Register (KORDERL): 0xD6
0x00
In registers KORDERL and KORDERH, Column Scan Order(14:0) is grouped into 5 sets of 3 bits each.
Each set determines which column (COL(4:0) pin) to activate by loading the column number into the 3
bits. When in HW_Scan_Enable mode, the hardware will step through the sets from 1Col to 5Col (up to
the number of columns in Colsize) and scan the column defined in the 3 bits. To scan in sequential
order, set a counting pattern with 0 in set 0, and 1 in set 1,and 2 in set 2, and 3 in set 3, and 4 in set 4.
The firmware should update this as part of the interrupt service routine so that the new scan order is
loaded prior to the next key being pressed. For example, to scan COL(0) first, 1Col(2:0) should be
loaded with 000’b. To scan COL(4) fifth, 5Col(2:0) should be loaded with 100’b.
