16.0   Digital Comparator (DCMP) / Pulse Width Modulator (PWM)

The SLG46140 has three 8-bit digital comparator / pulse width modulator logic cells. Each of these three logic cells can be either
a digital comparator (DCMP) or a pulse width modulator (PWM) independently of how the other two logic cells are defined.

Both the DCMP and PWM logic can operate at up to a frequency of 10MHz. The input power for the three logic cells is controlled
independently by reg<612> for DCMP0/PWM0, reg<601> for DCMP1/PWM1 and reg<590> for DCMP2/PWM2.

PWM power down control is configured by reg <653> which is also shared with the ADC and OSC.

16.1   DCMP Input Modes

The three DCMP logic cells have a positive (IN+) and a negative (IN-) input that are compared within the logic cell. The 

inp

 signal

(connected to the IN+ input) takes the value from a 4:1 mux selection between the following signals:

•

8-bit signal from the ADC Parallel Output

•

8-bit signal from the SPI logic cell output (SPI<15:8> for DCMP0 and DCMP2 or SPI<7:0> for DCMP1)

•

8-bit signal from the FSM0<7:0>

•

8-bit user defined signal value

The inn signal (connected to the IN- input) takes the value from a 4:1 mux selection between the following signals:

•

8-bit signal from the SPI logic cell output (SPI<7:0> for DCMP0 and DCMP2 or SPI<15:8> for DCMP1)

•

8-bit signal from the FSM0<7:0>

•

8-bit signal from the FSM1<7:0> (for DCMP0 and DCMP1) or CNT1'Q<7:0> (for DCMP2)

•

8-bit user defined signal value

16.2   DCMP Output Modes 

The two 8-bit data inputs from IN+ and IN- are compared within the DCMP logic cells to produce the output and a 

match

 signal.

•

If 

inp

 > 

inn

, both

 OUT+

 and 

OUT

 signals are equal to “1”, and 

EQ 

signal

 

is equal to “0”

•

If 

inp

 < 

inn

, both 

OUT+

 and 

OUT

 signals are equal to “0”, and 

EQ 

signal

 

is equal to “0”

•

If 

inp

 = 

inn

, both 

OUT+

 and 

OUT

 signals are equal to “0”, and 

EQ

 signal is equal to “1”

Both the 

OUT+ 

and 

EQ

 signals are triggered by the rising or falling edge of the 

CKOSC

 signal (defined by bit reg <580:579>). 

There are two cases for the OUT signal controlled by reg <614>, reg <603>, reg <592>.

If these registers = 0, then

•

if 

inp > inn

, OUT = 1, EQ = 0

•

if

 inp < inn

, OUT = 0, EQ = 0

•

if 

inp = inn

, OUT = 0, EQ = 1

If these registers = 1, then

•

if 

inp > inn

, OUT = 1, EQ = 0

•

if 

inp < inn

, OUT = 0, EQ = 0

•

if 

inp = inn

, OUT = 1, EQ = 1

16.3   PWM Input Modes 

IN+ for the PWM is an 8-bit data string that can be selected from one of four sources:

•

8-bit signal from the ADC Parallel Output
