Low Power Capacitive Touch Key Sensor
4.2. System control register
Index Default R/W Bit
Name
00 20 R/W 7-6 Reserved
5 SLOW_MODE_N
W 4 RST_CALB
3 ACT_INT_LVL
2 ACT_OUT_LVL
1 CTL_SLT
0 PWR_DN
Description
RC oscillator frequency adjust
1: Normal mode
0: Slow down mode
1: Reset calibration block
0: normal mode
Active interrupt level
1: High active
0: Low active
Active output level
1: High active
0: Low active
Control signal selection
1: From register setting
0: From input pin
1: Power down oscillator
0: Normal mode
(a) If MUC sends I2C command to set CTL_SLT, the function of control input pin will be disable.
Control signals include: SENSEn[2:0], WIN_CTL, MTM, PWMO_EN, PWMO_SLT, SLOW_MODE_N
(b) PWR_DN: MCU sends I2C command to enable/disable power down mode(sleep mode).
(c) After wake up, MCU must set RST_CALB=1 to reset calibration block and get new & correct calibration data.
