7.5.2.2.2
1. Enable the Bit0 in SNS_array[0] and Bit1 in SNSK_array[0] mask when enabling Channel0.
2. Enable the Bit2 in SNS_array[0] and Bit3 in SNSK_array[0] mask when enabling Channel1.
3. Enable the Bit4 in SNS_array[0] and Bit5 in SNSK_array[0] mask when enabling Channel2.
4. Enable the Bit6 in SNS_array[0] and Bit7 in SNSK_array[0] mask when enabling Channel3.
Example 1:
In a 4 channel library, two keys on channel 0 and 3 are enabled.SNS and SNSK on Port B
.Channel0 will B0B1 and Channel3 will be B6B7.
The SNS and SNSK masks will be
SNS_array[0]=0x41;
SNS_array[1]=0x00;
SNSK_array[0]=0x82;
SNSK_array[1]=0x00;
