ST92163 - MULTIFUNCTION TIMER (MFT)

MULTIFUNCTION TIMER (Cont’d)

8.2.3.9 TxINA = Clock Up - TxINB = Clock Down

The edge received on input pin A (or B) performs a

one step up (or down) count, so that the counter

clock and the up/down control are external. Setting

the UDC bit in the TCR register has no effect in

this configuration, and input pin B has priority on

input pin A.

8.2.3.11 TxINA = Trigger Up - TxINB = Trigger

Down

Up/down control is performed through both input

pins A and B. A edge on input pin A sets the up

count mode, while a edge on input pin B (which

has priority on input pin A) sets the down count

mode. The counter clock is internally generated,

and setting the UDC bit in the TCR register has no

effect in this configuration.

8.2.3.10 TxINA = Up/Down - TxINB = Ext Clock

An High (or Low) level applied to input pin A sets

the counter in the up (or down) count mode, while

the signal applied to input pin B is used as clock for

the prescaler. Setting the UDC bit in the TCR reg-

ister has no effect in this configuration.

8.2.3.12 TxINA = Up/Down - TxINB = I/O

An High (or Low) level of the signal applied on in-

put pin A sets the counter in the up (or down) count

mode. The counter clock is internally generated.

Setting the UDC bit in the TCR register has no ef-

fect in this configuration.
