TRIPLE TIMER (TEC)
This section describes a peripheral module composed of a common 21-bit prescaler and three
independent and identical general purpose 24-bit timer/event counters, each one having its
own register set.
Each timer can use internal or external clocking and can interrupt the DSP after a specified
number of events (clocks). Timer 0 can signal an external device after counting internal
events. Each timer can also be used to trigger DMA transfers after a specified number of
events (clocks) occurred. One timer (Timer 0) connects to the external world through one
bidirectional pin TIO0. When TIO0 is configured as input, the timer functions as an external
event counter or can measure external pulse width/signal period. When TIO0 is used as output
the timer is functioning as either a timer, a watchdog or a Pulse Width Modulator. When the
TIO0 pin is not used by the timer it can be used as a General Purpose Input/Output Pin. Refer
to Section 13 - Timer/ Event Counter.

ENHANCED SERIAL AUDIO INTERFACE (ESAI)
The ESAI provides a full-duplex serial port for serial communication with a variety of serial
devices including one or more industry-standard codecs, other DSPs, microprocessors, and
peripherals that implement the Motorola SPI serial protocol. The ESAI consists of
independent transmitter and receiver sections, each with its own clock generator. It is a
superset of the DSP56300 family ESSI peripheral and of the DSP56000 family SAI
peripheral. For more information on the ESAI, refer to Section 10 Enhanced Serial Audio
Interface (ESAI) on page 10-1.
1.5.5
ENHANCED SERIAL AUDIO INTERFACE 1 (ESAI_1)
The ESAI_1 is a second ESAI interface with just 6 dedicated pins instead of the 12 pins of the
full ESAI. Four data pins are shared with the ESAI, while the two high frequency clock pins
are not available. Other than the available pins, ESAI_1 is functionally identical to ESAI. For
more information on the ESAI_1, refer to Section 11 Enhanced Serial Audio Interface 1
(ESAI_1) on page 11-1.
