Bit provides manual connection of the IDAC to the analog global bus. The IDAC is automatically con-
nected when RO_EN = 1 or PXD_EN = 1.

IDAC output scaled to 1X range.
IDAC output scaled to 2X range.
IDAC output scaled to 4X range.
IDAC output scaled to 8X range.
IDAC sources current to analog global bus.
IDAC sinks current from analog global bus.
No manual connection
IDAC is connected to analog global bus.
No clock to I/O pins
Enabled pins switch between ground and the analog global bus. Clock rate selected by the
CLKSEL bits in the CS_CR1 register. Selected clock drives CapSense timer.
Relaxation oscillator disabled.
Relaxation oscillator enabled. Charging currents are set by the IRANGE bits and the
IDAC_D register value.
