ST92141 - 3-PHASE INDUCTION MOTOR CONTROLLER (IMC)

INDUCTION MOTOR CONTROLLER (Cont’d)

OUTPUT PERIPHERAL REGISTER (OPR)

R252 - Read/Write

Reset Value: 0000 0000 (00h)

Bit 7 = OPE:

Output Port Enable.

This bit can be set by software only if the NMI bit is

cleared.

0: Output port is in high impedance (without pull-

up and pull-down resistor).

1: Output port is available for data transfer.

Bit 6 = ODS:

Output Data Selection.

0: Dead time generator data.

1: Select the Bit 5:0 data

Bit 5:0 =

Uh, Ul, Vh, Vl, Wh, Wl phases

These bits can be sent out through the output port.

INTERRUPT MASK REGISTER (IMR)

R253 - Read/Write

Reset Value: 0000 0000 (00h)

Bit 7 = CM0E:

Compare 0 of PWM counter enable.

0: Disabled.

1: Enabled.

Bit 6 = CPTE:

Capture of Tacho counter Interrupt

enable.

0: Disabled.

1: Enabled.

Bit 5 = OTCE:

Overflow of Tacho counter Interrupt

enable.

0: Disabled.

1: Enabled.

Bit 4 = ADTE:

Automatic data transfer Interrupt

enable.

0: Disabled.

1: Enabled.

Bit 3 = ZPCE:

Zero of PWM counter interrupt ena-

ble.

0: Disabled.

1: Enabled.

Bit 2:0 = CPUE, CPVE, CPWE:

Compare U, V, W

interrupt enable.

0: Disabled.

1: Enabled.
