WATCHDOG
The microprocessor must periodically generate
this word; the value of the maximum period is set
by the capacitor CD. The absence of the Watch-
dog is interpreted by L6280 as a microprocessor
failure. The maximum period is:
TWD = CD x 1.5 / ( 50 x 10E-6)
Except for special words (keyword and watch-
dog), the input words are organized like the fol-
lowing:
A0 A1
Operation selection
A2 A3
Channel selection
D0 D1 D2 D3 Datas
A0,A1 DECODING (OPERATION SELECTION)
A0,A1select the type of operation (channel initiali-
zation, commands, DACs loading, DAC in-
crement/decrement).
A0 A1
0 0 This configuration is used to send the infor-
mation about the configuration of the
vchannel specified by A3 and A2; D0 to D3
are used to specify the configuration of the
channel (full bridge, dual half bridge, unipo-
lar motor).
A0 A1
1
0 This configuration is used to change driv-
ing strategy of the output stages of the
channel specified by A3 and A2 (full/half
step, slow/fast decay and so on). The driv-
ing strategy is coded in D0 to D3, and de-
pends from the configuration of the output
stage.
A0 A1
0 1 This configuration is used to load the value
of a DAC of the channel selected by A3
and A2. D3 indicates right and left DAC
just for channel 1 and 2.
