D7~D5: Data bits for test only
These bits are used for test purpose only and must be kept as “000” for normal
operations.

This register pair is used to store the touch key function 16-bit counter value. This 16-bit counter can
be used to calibrate the reference or key oscillator frequency. When the touch key time slot counter
overflows in the manual scan mode, this 16-bit counter will be stopped and the counter content will
be unchanged. However, this 16-bit counter content will be cleared to zero at the end of the time slot 0,
slot 1 and slot 2 but kept unchanged at the end of the time slot 3 in the auto scan mode. This register
pair will be cleared to zero when the TKST bit is set low.

This register pair is used to store the touch key module n 16-bit C/F counter value. This 16-bit C/
F counter will be stopped and the counter content will be kept unchanged when the touch key time
slot counter overflows in the manual scan mode. However, this 16-bit C/F counter content will be
cleared to zero at the end of the time slot 0, slot 1 and slot 2 but kept unchanged at the end of the
time slot 3 when the auto scan mode is selected. This register pair will be cleared to zero when the
TKST bit is set low.
