FSK modem (1200 bps) Circuit that automatically generates the start and stop bits used during FSK modulation Circuit that automatically generates the continuous mark signal at the start of transmission in FSK modulation mode Circuit that automatically inserts the idle bits (5 0r more bits) used in FSK modulation mode Built-in clock synchronous I/O shift register Detection ofall 16 DTMF signals
~ Perform one or two data moves ' Update one or two data address pointers ~ Perform a computation ~ Receive and transmit data via one or two serial ports Table I shows the features of each ADSP-216x processor
The triangle wave oscillator generates an essenlially symmetric rriangle wave using a timing capaciLor and resistor allached to the CT pin (pin l) and the RT pin (pin 2), respectively. The voltage amplitude is becween l.4 and 2.0 V wiLh pin 2 stabilized at l V. The oscillalor frequency is determined by the external capacirror and resistor.
