NXP Semiconductors K22F series - Registers Updated from Write Buffers

• QUADEN = 0
• DECAPEN = 0
• COMP = 1
In Complementary mode, the channel (n+1) output is the inverse of the channel (n)
output.
So, the channel (n+1) output is the same as the channel (n) output when:
• QUADEN = 0
• DECAPEN = 0
• COMP = 0
