Link 1 Counter 0 Clock Frequency Select
The clock input for counter 0 can be connected to an on-board clock generator operating at either
10KHz, 100KHz or 1MHz. This is set using LK1A/B/C.
Links 10-14 Power-Up Output State
These links are used to select the power-up state of the five groups of I/O channels. For more
information see page 4.
Links 20-24 Power-up control
Select whether the output buffer is always enabled or controlled by software. If you are configuring
the board for known boot up state then the group must be software enabled. If link B is fitted the
output state cannot be determined (‘don’t care’ state) at power up or reset.
Link IRQ2-5 & 7 Interrupt select
The output of counter 0 can be used to generate an interrupt on either IRQ 2,3,4,5 or 7.
NOTE: A PC must be configured with only one interrupt source for each interrupt line. Check your
PC configuration before selecting the interrupt signal. If you are not using the interrupt facility, it is
recommended that the jumper is not fitted.
