Ball characteristics

Table 3 provides a detailed description of SPEAr1340 pads and their terminal

characteristics.

Two levels of multiplexing are available:

●

Pad-level multiplexing

●

IP-level multiplexing

Figure 6 shows an overview of SPEAr1340 multiplexing scheme.

Figure 6.

SPEAr1340 multiplexing scheme

The multiplexed IPs are: GMAC, Keyboard, MCIF and FSMC. See Section 3.4: Multiplexed signals

description for more details.
