DAC Port
Table 13. DAC Port Data
The DAC port provides the CY7C63513C with 8 programmable
current sink I/O pins. Writing a “1” to a DAC I/O pin disables the
output current sink (Isink DAC) and drives the I/O pin HIGH
through an integrated 14 Kohm resistor. When a “0” is written to
a DAC I/O pin, the Isink DAC is enabled and the pull-up resistor
is disabled. A “0” output will cause the Isink DAC to sink current
to drive the output LOW. 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 the
two high current outputs that are programmable from a minimum
of 3.2 mA to a maximum of 16 mA (typical). DAC[7:2] are low
current outputs that are programmable from a minimum of 0.2
mA to a maximum of 1.0 mA (typical).
When a DAC I/O bit is written as a “1,” the I/O pin is either an
output pulled high through the 14 Kohm resistor or an input with
an internal 14 Kohm pull-up resistor. All DAC port data bits are
set to “1” during reset.
DAC Port Interrupts
A DAC port interrupt can be enabled/disabled for each pin
individually. The DAC Port Interrupt Enable register provides this
feature with an interrupt mask bit for each DAC I/O pin. Writing

a “1” to a bit in this register enables interrupts from the
corresponding bit position. Writing a “0” to a bit in the DAC Port
Interrupt Enable register disables interrupts from the
corresponding bit position. All of the DAC Port Interrupt Enable
register bits are cleared to “0” during a reset.
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
will cause 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 will cause 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.
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].
