S3C6410_CIRCUIT DESIGN GUIDE REV 1.00
23.2 Pin Connection Example
Figure 23_1) Modem I/F Pin connection example
23.3 Caution
(1) Voltage level is same between MODEM(memory bus and EXINT) and AP(MODEM I/F). Confirm the
datasheet what you want to use.
(2) There is only one interrupt request pin from AP to MODEM(XhiINTR). Any other extra interrupt request pin
needs not between AP and modem because interrupt requests from modem to AP are delivered through
Xhi_A[12:0] and Xhi_D[16:0] by writing some value to INT2AP register of DPSRAM in AP.
(3) If you use AP booing function, you must connect the CS(Chip Select) which is used to boot-up your device
to S3C6410's CS(XhiCSn).
(4) Refer the datasheet's timing specification.
(5) Address connection between MODEM and AP follows the memory controlling policy of MODEM.
