are set to ‘0’ when the device is suspended, that DAC input will float. The floating pin could result in excessive current consumption
by the device, unless an external load places the pin in a deterministic state.
DAC Port Data
Bit [1..0]: High Current Output 3.2 mA to 16 mA typical
resistor.
Bit [7..2]: Low Current Output 0.2 mA to 1 mA typical
resistor.
10.1
Each DAC I/O pin has an associated DAC Isink register to program the output sink current when the output is driven LOW. The
first Isink register (0x38) controls the current for DAC[0], the second (0x39) for DAC[1], and so on until the Isink register at 0x3F,
controls the current to DAC[7].
DAC Sink Register
Bit [4..0]: Isink [x] (x= 0..4)
Bit [7..5]: Reserved
10.2
A DAC port interrupt can be enabled/disabled for each pin individually. The DAC Port Interrupt Enable register provides this
feature with an interrupt enable bit for each DAC I/O pin. All of the DAC Port Interrupt Enable register bits are cleared to ‘0’ during
a reset. All DAC pins share a common interrupt, as explained in Section 16.7.
DAC Port Interrupt
Bit [7..0]: Enable bit x (x= 0..7)
As an additional benefit, the interrupt polarity for each DAC pin is programmable with the DAC Port Interrupt Polarity register.
Writing a ‘0’ to a bit selects negative polarity (falling edge) that causes an interrupt (if enabled) if a falling edge transition occurs
on the corresponding input pin. Writing a ‘1’ to a bit in this register selects positive polarity (rising edge) that causes an interrupt
(if enabled) if a rising edge transition occurs on the corresponding input pin. All of the DAC Port Interrupt Polarity register bits are
cleared during a reset.

1= I/O pin is an output pulled HGH through the 14-k
1= I/O pin is an output pulled HGH through the 14-k
DAC Isink Registers
Writing all ‘0’s to the Isink register causes 1/5 of the max current to flow through the DAC I/O pin. Writing all ‘1’s to the
Isink register provides the maximum current flow through the pin. The other 14 states of the DAC sink current are evenly
spaced between these two values.
DAC Port Interrupts
1= Enables interrupts from the corresponding bit position; 0= Disables interrupts from the corresponding bit position
