Description
Timer 0 External Clock Input
When timer 0 operates as a counter, a falling edge on the T0 pin increments
the count.
Timer 1 External Clock Input
When timer 1 operates as a counter, a falling edge on the T1 pin increments
the count.
Description
DAC Data Bit Clock
DAC Audio Data
DAC Channel Select Signal
DSEL is the sample rate clock output.
DAC System Clock
SCLK is the oversampling clock synchronized to the digital audio data (DOUT)
and the channel selection signal (DSEL).
Description
USB Positive Data Upstream Port
This pin requires an external 1.5 KΩ pull-up to V
USB Negative Data Upstream Port
Description
MMC Clock output
Data or command clock transfer.
MMC Command line
Bidirectional command channel used for card initialization and data transfer
commands. To avoid any parasitic current consumption, unused MCMD input
must be polarized to V
