LPC2917/01; LPC2919/01
ARM9 microcontroller with CAN and LIN
The actual PWM consists of two counters; a 16-bit prescale counter and a 16-bit PWM
counter. The position of the rising and falling edges of the PWM outputs can be
programmed individually. The prescale counter allows high system bus frequencies to be
scaled down to lower PWM periods. Registers are available to capture the PWM counter
values on external events.
Note that in the Modulation and Sampling SubSystem, each PWM has its individual clock
source CLK_MSCSS_PWMx (x runs from 0 to 3). Both the prescale and the timer
counters within each PWM run on this clock CLK_MSCSS_PWMx, and all time references
are related to the period of this clock. See
Section 6.15
for information on generation of
these clocks.
6.14.5.2
Synchronizing the PWM counters
A mechanism is included to synchronize the PWM period to other PWMs by providing a
sync input and a sync output with programmable delay. Several PWMs can be
synchronized using the trans_enable_in/trans_enable_out and sync_in/sync_out ports.
See
Figure 8
for details of the connections of the PWM modules within the MSCSS in the
LPC2917/2919/01. PWM 0 can be master over PWM 1; PWM 1 can be master over
PWM 2, etc.
6.14.5.3
Master and slave mode
A PWM module can provide synchronization signals to other modules (also called Master
mode). The signal sync_out is a pulse of one clock cycle generated when the internal
PWM counter (re)starts. The signal trans_enable_out is a pulse synchronous to sync_out,
generated if a transfer from system registers to PWM shadow registers occurred when the
PWM counter restarted. A delay may be inserted between the counter start and
generation of trans_enable_out and sync_out.
A PWM module can use input signals trans_enable_in and sync_in to synchronize its
internal PWM counter and the transfer of shadow registers (Slave mode).
6.14.5.4
Pin description
Each of the four PWM modules in the MSCSS has the following pins. These are combined
with other functions on the port pins of the LPC2917/2919/01.
Table 23
shows the PWM0
to PWM3 pins.
