The amount of sink current for the DAC I/O pin is programmable
over 16 values based on the contents of the DAC Isink Register
for that output pin. DAC[1:0] are high-current outputs that are
programmable from 3.2 mA to 16 mA (typical). DAC[7:2] are
low-current outputs, programmable from 0.2 mA to 1.0 mA
(typical).
When the suspend bit in Processor Status and Control Register

1= I/O pin is an output pulled HGH through the 14-k resistor.
0 = I/O pin is an input with an internal 14-k pull-up resistor
Bit [3..2]: Low Current Output 0.2 mA to 1 mA typical
1= I/O pin is an output pulled HGH through the 14-k resistor.
0 = I/O pin is an input with an internal 14-k pull-up resistor

circuitry is disabled. Special care should be taken when the
CY7C64x13C device is placed in the suspend mode. The DAC
Port Data Register (see
with all ‘1’s (0xFF) before setting the suspend bit. If any of the
DAC bits 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 Isink Registers
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].
