HS USB PCI Host Controller
7.7 Legacy support
The ISP1563 provides legacy support for a USB keyboard and mouse. This means that
the keyboard and mouse must be able to work even before the Operating System (OS)
boot-up, with the necessary support in the Basic Input Output System (BIOS).
Section 11.2 provides a detailed description on the legacy support in the ISP1563.
7.8 Phase-Locked Loop (PLL)
A 12 MHz-to-30 MHz and 48 MHz clock multiplier PLL is integrated on-chip. This allows
the use of a low-cost 12 MHz crystal, which also minimizes EMI. No external components
are required for the PLL to operate.
7.9 Power-On Reset (POR)
Figure 3 shows a possible curve of VCC(I/O) with dips at t2 to t3 and t4 to t5. At t0, POR will
start with 1. At t1, the detector passes through the trip level. Another delay will be added
before POR drops to 0 to ensure that the length of the generated detector pulse, POR, is
large enough to reset asynchronous ip-ops. If the dip is too short (t4 to t5 < 11
s), POR
will not react and will stay LOW.
7.10 Power supply
Figure 4 shows the ISP1563 power supply connection.
VPOR(trip) is typically 1.2 V.
