Table 599: D/A Converter Register (DACR - address 0xE006 C000) bit description
Bits 21:20 of the PINSEL1 register
(PINSEL1 - 0xE002 C004)” on page
controlling the state of pin P0.26/AD0.3/AOUT/RXD3. When these bits are 10, the DAC is
powered on and active.
The settling times noted in the description of the BIAS bit are valid for a capacitance load
on the AOUT pin not exceeding 100 pF. A load impedance value greater than that value
will cause settling time longer than the specified time. One or more graph(s) of load
impedance vs. settling time will be included in the final data sheet.

Description
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
After the selected settling time after this field is written with a
new VALUE, the voltage on the A
is VALUE/1024 × VREF.
The settling time of the DAC is 1 μ s max, and the maximum
current is 700 μ A.
The settling time of the DAC is 2.5 μ s and the maximum
current is 350 μ A.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
