Generation of up to 4-pulse signal with controlled output enable and configurable initial state
Interrupt
A single PWM cycle can have up to 4 pulses (8 edges). The PWM block uses a 16-bit counter to
determine the period of a single PWM cycle. This counter counts system clocks which can also be divided
by an optional 8-bit prescaler. The PWM drivers allow the user to select when PWM output toggles. These
values correspond to the values of 16-bit counter. For example, on the timing diagram below - Figure
6.24, the 16-bit counter counts to 23 and pwm_out[0] output toggles when the counters current value is
equal to 7, 8, 12, 14, 15, 16, 19 and 22.
Figure 6.24 PWM – Timing Diagram
The user can also select the initial state of each of the PWM outputs (HI or LOW). PWM outputs can also
be enabled continuously or a cycle can be repeated 1..255 times. The PWM cycle can be started by the
PWM driver or externally using a trigger input.
6.10 General Purpose Input Output
VNC2 provides up to 40 configurable Input/Output pins depending on the package. The Input/Output pins
are connected to Ports A through E. These ports are controlled by the VNC2 CPU. All ports are
configurable to be either inputs or outputs and allow level or edge driven interrupts to be generated.
To simplify the use of the 40 available GPIO signals, they have been grouped into 5 "ports", identified as
A, B, C, D and E. Each port is 1 byte wide and the RTOS drivers will allow each port to be individually
accessed.
Each GPIO signal is mapped on to a bit of the port value. For example, gpio[A0] is the least significant
bit of the value read from or written to GPIO port A. Similarly, gpio[A7] is the most significant bit of the
value read from or written to GPIO port A (see Figure 6.25 GPIO Port Groups)
Each pin can be individually configured as input or output. GPIO port A supports an interrupt that can be
used to detect a state change of any of its 8 pins. Port B features a more sophisticated set of 4
configurable interrupts that can be associated with individual pins and supports several conditions such
as positive edge, negative edge, high or low.
