Bit [4..0]: Isink [x] (x= 0..4)
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.
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 16.6.

Bit [7..0]: Enable bit x (x= 0..2, 7)
1= Enables interrupts from the corresponding bit position; 0= Disables interrupts from the corresponding bit position
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.

12-Bit Free-Running Timer
The 12-bit timer provides two interrupts (128-μs and 1.024-ms) and allows the firmware to directly time events that are up to 4
ms in duration. The lower 8 bits of the timer can be read directly by the firmware. Reading the lower 8 bits latches the upper 4
bits into a temporary register. When the firmware reads the upper 4 bits of the timer, it is accessing the count stored in the
temporary register. The effect of this logic is to ensure a stable 12-bit timer value can be read, even when the two reads are
separated in time.
