OPERATION

PWM Waveform Output

Serial Data Input

(1)12-bit PWM output

When chip select CS is “L” and write control input WR is “L”,

data input to SIN at the edge where write clock input SCLK sta-

tus shifts from “L” to “H” is written. (See Fig. 3.)

One PWM waveform cycle is divided into 16(2⁴) subsec-

tions t, and each subsection is further divided into 256 (2⁸)

minimum resolution bits τ (= 2/fXIN)

At the edge where WR rises from “L” to “H”, the latest 8-bit

data writing is completed, and input data is stored in lower (or

upper) byte register. When writing on the lower byte or writing

on both upper and lower bytes is completed, data on the

lower byte register or, in the latter case, data on both lower

and upper byte registers is written on the PWM register of the

channel designated by lower bytes b2 and b1. All setting pro-

cess ends with this writing, and PWM waveform changes ac-

cording to the setting from the next cycle.

The “H” width of subsection t basic waveform is deter-

mined by the upper 8 bits of PWM data.

(In Fig. 2 above, “H” width is 4A16 = 74 × τ)

Among these 16 subsections t, subsections tm designated

by the lower 4 bits of PWM data have “H” width that is

longer by τ.

[In Fig. 2 above, the “H” width of designated 6 subsections

(m =2, 4, 6, 10, 12 and 14) is 4B16 = 75 × τ.]
