Table 5. Reset Timing Values
3.9.2 Wakeup Pins
The 8051 puts itself and the rest of the chip into a power down
mode by setting PCON.0 = 1. This stops the oscillator and PLL.
When WAKEUP is asserted by external logic the oscillator
restarts after the PLL stabilizes, and the 8051 receives a wakeup
interrupt. This applies whether or not FX2LP is connected to the
USB.
The FX2LP exits the power down (USB suspend) state using one
of the following methods:
■
■
■
The second wakeup pin, WU2, can also be configured as a
general purpose I/O pin. This enables a simple external R-C
network to be used as a periodic wakeup source. WAKEUP is by
default active LOW.

3.10 Program/Data RAM
3.10.1 Size
The FX2LP has 16 KBytes of internal program/data RAM, where
PSEN#/RD# signals are internally ORed to enable the 8051 to
access it as both program and data memory. No USB control
registers appear in this space.
Two memory maps are shown in the following diagrams:

Figure 4
3.10.2 Internal Code Memory, EA = 0
This mode implements the internal 16 KByte block of RAM
(starting at 0) as combined code and data memory. When
external RAM or ROM is added, the external read and write
strobes are suppressed for memory spaces that exist inside the
chip. This enables the user to connect a 64 KByte memory
without requiring address decodes to keep clear of internal
memory spaces.
Only the internal 16 KBytes and scratch pad 0.5 KBytes RAM
spaces have the following access:

■
3.10.3 External Code Memory, EA = 1
The bottom 16 KBytes of program memory is external and
therefore the bottom 16 KBytes of internal RAM is accessible
only as a data memory.
