‘Externally driven’ refers to logic outside the ISP1181.
When external components are powered-off, it is possible that interface signals RD,
WR and CS have unknown values immediately after leaving ‘suspend’ state. To
prevent corruption of its internal registers, ISP1181 enables a locking mechanism
once suspend is enabled.
After wake-up from suspend’ state, all internal registers except the Unlock Register
are write-protected. A special unlock operation is needed to re-enable write access.
This prevents data corruption during power-up of external components.
Figure 9
shows a typical bus-powered modem application using ISP1181 in
powered-off mode. The SUSPEND output is used to switch off power to the
microcontroller and other external circuits during ‘suspend’ state. The ISP1181 is
woken up via the USB bus (global resume) or by the ring detection circuit on the
telephone line.
