// Example code: low-level register access.
// The MAX4455 Evaluation Software uses a bidirectional parallel port under windows.
// Practical applications should use a microprocessor memory or I/O bus.
// User-defined subroutine to wait until READY/BUSY signal is READY.
// Return false if the BUSY signal seems to be stuck low.
