IS 16 bit data using PWm applicable with LC21xx.Other way around Can PWM work with 16 bit file
 

pwm is pulse width modulation

given that a pulse is a single bit

in terms of a 16 bit dword
you have avalible 15 marks to a single space

ie if you send all 16 bits width of time
you can encode 15 bits of width within its space...
if you still need a space bit to sync
or using an invert output you can encode a further 16 bits

if you 'switch mode' {yes hence the psu term}
before you shoot me down study the meaning of switch mode and also switched mode both terms apply to digital control of a psu... or a digital mark space system

so you have 32 bits

but in combination some 32 X 32 possible entities within the time frame of 16bits
you can further encode this with spent cycles for epcwm

however pulse width in this form we both discribe boarders on pulse code width
{pcwm} just by its digital nature


pwm is for ramping in the analogue world
digital belongs to encoding mark width and space width as bits of width by bits of space

so they dont share the same paradym

pwm is analogue and granular by magnitudes of mega bytes
or should be...
 

Basically yes, but the PWM cycle frequency is limited of course (fclk/2^16).
