Description
This is an 8-bit value that selects the number of current units that combine to form the IDAC current.
This current then drives the analog mux bus when IDAC mode is enabled. For example, a setting of
80h means that the charging current is 128 current units.
The current size also depends on the IRANGE setting in the CS_CR2 register. This setting supplies
the charging current for the relaxation oscillator. This current and the external capacitance connected
to the analog global bus determines the RO frequency.
This register is also used to set the charging current in the proximity detect mode.
Step size is approximately 330 nA/bit for default IRANGE state 00b.
