PWM characteristics
Characteristics of the PWMs are as follows:
D 16-bit registers
D Programmable deadband for the PWM output pairs, from 0 to 12 s
D Minimum deadband width of 25 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
D The PWM pins are driven to a high-impedance state when the PDPINTx pin is driven low and after PDPINTx
signal qualification. The PDPINTx pin (after qualification) is reflected in bit 8 of the COMCONx register.
PDPINTA pin status is reflected in bit 8 of COMCONA register.
PDPINTB pin status is reflected in bit 8 of COMCONB register.
capture unit
The capture unit provides a logging function for different events or transitions. The values of the selected GP
timer counter is captured and stored in the two-level-deep FIFO stacks when selected transitions are detected
on capture input pins, CAPx (x = 1, 2, or 3 for EVA; and x = 4, 5, or 6 for EVB). The capture unit consists of three
capture circuits.
Capture units include the following features:
D One 16-bit capture control register, CAPCONx (R/W)
D One 16-bit capture FIFO status register, CAPFIFOx
D Selection of GP timer 1/2 (for EVA) or 3/4 (for EVB) as the time base
D Three 16-bit 2-level-deep FIFO stacks, one for each capture unit
D Three capture input pins (CAP1/2/3 for EVA, CAP4/5/6 for EVB)—one input pin per 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 CAP1/2 and CAP4/5 can also
be used as QEP inputs to the QEP circuit.]
D User-specified transition (rising edge, falling edge, or both edges) detection
D Three maskable interrupt flags, one for each capture unit
quadrature-encoder pulse (QEP) circuit
Two capture inputs (CAP1 and CAP2 for EVA; CAP4 and CAP5 for EVB) 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 2/4 is incremented or decremented
by the rising and falling edges of the two input signals (four times the frequency of either input pulse).
