OK, TKSF=1

Fail, TKPESF=1

Control the TKCSR register to adjust touch key sensitivity. TKCSR =0x00 has a higher

sensitivity, whereas TKCSR= 0x0F has a lower sensitivity.

In some high noise environment or waterproof applications, user can adjust the TKSWR

with less noise & sensing data. On the other hand, TKSWR =0x1F is a big sensing window

with greater noise & sensing data.

6.7.3 Touch Key Idle-Scan mode

This body support Idle-Scan touch key in IDLE mode. User can enable it by setting the

TKISE. In this mode, when the CPU enters into Idle mode, it will interval some time to scan

the touch key automatically. Also, touch and pins will be combined to scan together.
