Audio Interface Signal Description
USB Controller Signal Description
MutiMediaCard Interface Signal Description
Description
Timer 1 Gate Input
INT1 serves as external run control for timer 1, when selected by GATE1 bit in
TCON register.
External Interrupt 1
INT1 input sets IE1 in the TCON register. If bit IT1 in this register is set, bit IE1
is set by a falling edge on INT1#. If bit IT1 is cleared, bit IE1 is set by a low
level on INT1#.
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 Output
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
