manager
This block includes the 5.0 V-to-3.3 V regulator and power source selection.
6.2.5. Audio
interface
This block provides stereo audio line IN interface and microphone (with pre-amp) OUT interface. Its main
purpose is to demonstrate the carkit application (play audio or voice with carkit).

7.1.
DB-25 PC parallel port connector (J10) pin assignment
J10 is used to connect to the PC parallel port through the DB-25 printer cable. Table 7-1 shows its pin assignment.

8-bit microprocessor interface 20 x 2 header (J13) pin assignment
J13 is used to connect to a generic 8-bit parallel bus microprocessor controller. The bus uses the Intel
®
mode.
Required signals include D0–D7, A0, WR_N, RD_N, CS_N, INT1 and INT2. Table 7-2 shows the pin assignment
for J13.
Note: We use a 20 x 2 header to make it compatible with the Philips ISP1362 and ISP1161x ISA interface boards.

Note: An external OTG Controller system can use the CHRG_EN signal to enable or disable +5.0 V from the
V
BUS
line of the mini-AB connector to pin 2 of J2. This is useful when an analog audio carkit is attached and the
carkit can charge the external battery.
7.3.
USB OTG Controller interface 8 x 2 header (J8 and J3) pin assignment
Header connectors J8 and J3 are used to connect the ISP1301 to the OTG Controller core. J8 includes the USB
Serial Interface Engine (SIE) signals—DAT_VP, SE0_VM, RCV and OE_TP_INT_N—and I
2
C signals—SDA, SCL and
INT_N. J3 also includes other signals that may be used by selected OTG Controller.
