Block Diagram

Figure 3.17.1 shows a block diagram of the SPIC and its connections with a SD card.

SPIC (SPI Controller)

Note 1: The SPCLK, SPCS , SPDO and SPDI pins are configured as input ports (Ports PR3, PR2, PR1 and PR0)

Thus, these pins require pull-up resisters to fix their voltage levels. The pull-up resistor values should be

adjusted under real-world conditions.

Note 2: Any one of general inputs and interrupt should be used as the WP (Write Protect) and CD (Card Detect)

inputs, respectively.
