PWM characteristics
Characteristics of the PWMs are as follows:
D 16-bit registers
D Programmable deadband for the PWM output pairs, from 0 to 24 s
D Minimum deadband width of 50 ns
D Change of the PWM carrier frequency for PWM frequency wobbling as needed
D Change of the PWM pulse widths within and after each PWM period as needed
D External-maskable power and drive-protection interrupts
D Pulse-pattern-generator circuit, for programmable generation of asymmetric, symmetric, and four-space
vector PWM waveforms
D Minimized CPU overhead using auto-reload of the compare and period registers
capture unit
The capture unit provides a logging function for different events or transitions. The values of the GP timer 2
counter are captured and stored in the two-level FIFO stacks when selected transitions are detected on capture
input pins, CAPx for x = 1, 2, or 3. The capture unit of the TMS320x24x consists of three capture circuits.
D Capture units include the following features:
One 16-bit capture control register, CAPCON (R/W)
One 16-bit capture FIFO status register, CAPFIFO
Selection of GP timer 2 as the time base
Three 16-bit 2-level-deep FIFO stacks, one for each capture unit
Three capture input pins CAP1, CAP2, and CAP3, one input pin per each capture unit. [All inputs are
synchronized with the device (CPU) clock. In order for a transition to be captured, the input must hold at
its current level to meet two rising edges of the device clock. The input pins CAP1 and CAP2 can also be
used as QEP inputs to the QEP circuit.]
User-specified transition (rising edge, falling edge, or both edges) detection
Three maskable interrupt flags, one for each capture unit
quadrature-encoder pulse (QEP) circuit
Two capture inputs (CAP1 and CAP2) can be used to interface the on-chip QEP circuit with a quadrature
encoder pulse. Full synchronization of these inputs is performed on-chip. Direction or leading-quadrature pulse
sequence is detected, and GP timer 2 is incremented or decremented by the rising and falling edges of the two
input signals (four times the frequency of either input pulse).
