Description

Touch control register

Fields

TOUCH_DRANGE

TOUCH attenuation.
TOUCH_DREFL

TOUCH reference voltage low. 0: 0.5 V 1: 0.6 V 2: 0.7 V 3: 0.8 V.
TOUCH_DREFH

TOUCH reference voltage high. 0: 2.4 V 1: 2.5 V 2: 2.6 V 3: 2.7 V.
TOUCH_XPD_BIAS

TOUCH BIAS power switch.
TOUCH_REFC

Touch pad 0 reference capacitance.
TOUCH_DBIAS

0: Use bandgap bias. 1: Use self bias.
TOUCH_SLP_TIMER_EN

Touch timer enable bit.
TOUCH_START_FSM_EN

0: TOUCH_START and TOUCH_XPD are controlled by soft- ware. 1: TOUCH_START and TOUCH_XPD are controlled by the Touch FSM.
TOUCH_START_EN

1: Start the Touch FSM, only valid when RTC_CNTL_TOUCH_START_FORCE = 1.
TOUCH_START_FORCE

0: Start the Touch FSM by timer. 1: Start Touch FSM by software.
TOUCH_XPD_WAIT

The waiting cycles (in 8MHz) between TOUCH_START and TOUCH_XPD.
TOUCH_SLP_CYC_DIV

When a touch pad is active, sleep cycle could be divided by this number.
TOUCH_TIMER_FORCE_DONE

Force touch timer done.
TOUCH_RESET

Reset TOUCH FSM via software.
TOUCH_CLK_FO

Touch clock force on.
TOUCH_CLKGATE_EN

Touch clock enable bit.
