INPUT/OUTPUT with selectable pull up resistor. General purpose memory
mapped I/O port bit. This pin can be configured as active low HOLD acknowledge.
In Emulation mode HOLDACKn is automatically selected.
INPUT/OUTPUT with selectable pull up resistor. General purpose memory
mapped I/O port. In development mode this pin generates an ISE interrupt to the
CR16A core if high.
INPUT/OUTPUT with open drain with 100 mA sink capability. If P1[7] is configured
as READY pin then if HOLDn is ‘1’, this pin will become low upon a read or write
access by an external processor. Can be used to control a LED connected to VDD..
Digital supply voltage.
Digital ground.
INPUT/OUTPUT with open drain with 100mA sink capability. This pin can also be
configured as single ended buzzer driver.
INPUT/OUTPUT. General purpose memory mapped I/O port bit. P2[1,2] can be
configured as complementary PWM output for e.g. buzzer control. P2[1,2] can
drive 12 mA.
INPUT/OUTPUT. General purpose memory mapped I/O port bit. P2[1,2] can be
configured as complementary PWM output for e.g. buzzer control. P2[1,2] can
drive 12 mA.
INPUT/OUTPUT. General purpose memory mapped I/O port bit.
OUTPUT External interface strobe 0.
INPUT/OUTPUT. General purpose memory mapped I/O port bit.
INPUT/OUTPUT. External interface strobe STR1.
INPUT. Testpin
INPUT/OUTPUT. External interface clock. On rising edge data is valid.
INPUT/OUTPUT. External interface data input, codec output. If output, this pin is
configured as an open drain. If the internal codec is used (format 1) an external pull
up resistor is required.
INPUT/OUTPUT. PCM interface data output, codec input
INPUT. TONE input to capture timer (e.g. metering tones)
DIGITAL OUTPUT/ANALOG INPUT. General purpose input to 8 bit ADC. 8 bit DAC
if ADC0,1,2 are not selected. P2[5] can also be used as a digital output.
DIGITAL OUTPUT/ANALOG INPUT. General purpose input one to 8 bit ADC
P2[6] can also be used as a digital output.
DIGITAL OUTPUT/ANALOG INPUT. General purpose input two to 8 bit ADC.
P2[7] can also be used as a digital output.
OUTPUT. Positive microphone reference voltage.
INPUT. Microphone positive input.
Signal ground output.
INPUT. Microphone negative input.
OUTPUT. Negative microphone reference voltage.
OUTPUT. Negative loudspeaker output.
OUTPUT. Positive loudspeaker output
Analog supply.
Analog ground.
OUTPUT. 8 bit DAC output e.g. for frequency control
External capacitor for crystal oscillator.
INPUT. 10.368 MHz crystal connection.
Digital ground.
Positive supply voltage.
