January 2001
Production Data
The description for the VCCP pin has been modified. This informa-
tion can be found in Table 2, LF240x Pin List and Package Options.
The conditions for high-impedance state for the strobe signals have
been changed. This information can be found in Table 2, LF240x Pin
List and Package Options.
The th(A)COLW parameter is now referenced from the next falling
CLKOUT edge than what was shown in the previous data sheets.
The specification for this parameter is 5 ns (MIN).
Ready-on-Read and Ready-on-Write timings for one software wait
state and one external wait state have been added.
Bits 15 and 8 of the SCSR1 register are now reserved
(see Table 19, LF240x DSP Peripheral Register Description).

August 2001
Production Data
Updated description of TMS2 in Table 2.
Updated Figure 6, Event Manager A Block Diagram. TCLKINx is
now routed through the prescaler.
Updated the ADC module list of functions in the Enhanced Analog-
to-Digital Converter (ADC) Module section (p.39).
The I/O buffers used in 240x/240xA are
not
5-V compatible.
Updated the fCLKOUT parameter in the Recommended Operating
Conditions table (p.62).
Updated the tc(AD) and tw(SHC) parameters in the Internal ADC Mod-
ule Timings table of the 10-Bit Analog-to-Digital Converter (ADC)
section (p.97).
Updated PDDATDIR register (0x0709E) in Table 19, LF240x DSP
Peripheral Register Description.
