Pamux User’s Guide 107
TURN OFF RESET
Before reading from or writing to any Pamux station, you must make sure a reset is not being requested.
To do so you will need to turn off the reset if it is configured on the brain board as active high, or turn on
the reset if it is configured as active low. (See Chapter 3 to review the positions of the reset jumpers on
the brain boards.)
OUT MyAc28ResetPort%, NOT MyAc28ResetLevel%
‘ Restore reset line
RESETTING THE SYSTEM
The following example pulses the reset line. First, it asserts the reset line by turning it on if it is active
high, turning it off it is active low. Then, after a brief time interval, it returns the reset line to its normal
state. The subroutine MyKillTime is used to pause the routine (see “Common Subroutines” at the end of
this chapter for specifics).
DECLARE SUB MyKillTime ()
OUT MyAc28ResetPort%, MyAc28ResetLevel%
‘ Reset I/O
CALL MyKillTime
‘ Wait at least 20 ms
OUT MyAc28ResetPort%, NOT MyAc28ResetLevel%
