Versatile-Timer-Unit (VTU)
The Versatile Timer Unit (VTU) contains four fully indepen-
dent 16-bit timer subsystems. Each timer subsystem can op-
erate either as dual 8-bit PWM timers, as a single 16-bit
PWM timer, or as a 16-bit counter with 2 input capture chan-
nels. These timer subsystems offers an 8-bit clock prescaler
to accommodate a wide range of system frequencies.
The Versatile Timer Unit offers the following features:
The Versatile Timer Unit (VTU) can be configured to pro-
vide:
— Eight fully independent 8-bit PWM channels
— Four fully independent 16-bit PWM channels
— Eight 16-bit input capture channels
The VTU consists of four timer subsystems, each of which
contains:
— a 16-bit counter
— two 16-bit capture / compare registers
— an 8-bit fully programmable clock prescaler
Each of the four timer subsystems can operate in the fol-
lowing modes:
— low power mode, i.e. all clocks are stopped
— dual 8-bit PWM mode
— 16-bit PWM mode
— dual 16-bit input capture mode
The Versatile-Timer-Unit controls a total of eight I/O pins,
each of which can function as either:
— PWM output with programmable output polarity
— Capture input with programmable event detection and
timer reset
A flexible interrupt scheme with
— four separate system level interrupt requests
— a total of 16 interrupt sources each with a separate in-
terrupt pending flag and interrupt enable bit
16.1
The Versatile-Timer-Unit (VTU) is comprised of four timer
subsystems. Each timer subsystem contains an 8-bit clock
prescaler, a 16-bit up-counter and two 16-bit registers. Each
timer subsystem controls two I/O pins which either function
as PWM outputs or capture inputs depending on the mode of
operation. There are four system level interrupt requests, one
for each timer subsystem. Each system level interrupt re-
quest is controlled by four interrupt pending flags with asso-
ciated enable/disable bits. All four timer subsystems are fully
independent and each may operate as a dual 8-bit PWM tim-
er, a 16-bit PWM timer or as a dual 16-bit capture timer. Fig-
ure 18 illustrates the main elements of the Versatile-Timer-
Unit (VTU).
