2.3 Remote wake-up function
The remote wake-up function is also supported by the evaluation board. By pressing SW3
(ST7262xxx) or SW2 (ST7263Bxx) you can wake up the PC from standby mode.
Under Windows XP, the remote wake-up capability should be enabled. For that you should
go to the “Device Manager” then “Human Interface Device” and “HID-compliant device”. On
the tabsheet “Power Management”, select “Allow this device to bring the computer out of
standby”.
2.4 Adding circuitry on the wire-wrap area
The evaluation board features a 43-hole row with all the microcontroller pins plus one side of
the analog trimmer. These connection points can be used for signal probing or rewiring to
the wire-wrap area.
Table 1 gives the definition of these points for each MCU used.
