ADS Functional Description
5.7.5 Power Manager
The power manager is the Power-One ZM7108 controller, and this device stores all power
system parameters. Access to it is available from a shared I
host MPC8560 or from the MSC8144. Updated values for this controller may be programmed in
internal non-volatile memory.
5.8 SPI Bus
There are two SPI master devices (MPC8560 and MSC8144) and four slave devices (two
DS26521 E1/T1 Framers, a 7380 RGMII switch, and an ICS30703 Clock Synthesizer). Serial
Flash memory is accessed from MSC8144 only. The SPI bus connection is shown in Figure 5-7.
Four GPIO pins (GPIO18,GPIO16,GPIO1,GPIO0) enable selecting the different SPI bus parts. The
coding for this is shown in Table 5-5. This feature requires a disable signal on the SPI Select lines driving
from the Host (
in the OFF position.
