INTERRUPT MASK REGISTER

Address: 0x00B, Reset: 0x4000, Name: MASK

If a bit in the MASK register is set, the associated status flag generates an interrupt, with the exception of Bit 15, DREADY, as described in

Table 29.

15

DREADY

ADC Waveform Sample Interrupt Enable. Set this bit to 1 to enable 100 kHz interrupts

synchronized when ADC samples are ready. When this bit is enabled, all other interrupts must

be disabled with MASK register, Bits[14:0] equal to zero.

COOLDOWN1

Channel 1 Cool Down Mode Interrupt Enable. Set this bit to 1 to get an indication when channel

1 is in cool down mode to keep the device within a safe operating mode as configured by the

internal FET power meter.

TSD

Programmable Load Thermal Shutdown Interrupt Enable. Set this bit to 1 to get an indication

when the programmable load has been disabled due to thermal protection.

0x0

R/W

9

COMFLT

Isolated Communication Error Interrupt Enable. Set this bit to 1 to get an indication when there

is an error in the internal data communicated between the isolated and nonisolated sides of the

device. The device deals with retransmitting packets. If this error persists after writing a 1 to the

COMFLT bit in the INT_STATUS register, then reconfigure the register settings in the device.

MEMFLT

Memory Fault Interrupt Enable. Set this bit to 1 to get an indication when there is a mismatch

between the register values on the isolated and nonisolated sides of the device, indicating the

registers must be reconfigured.

INTERRUPT STATUS REGISTER

Address: 0x00C, Reset: 0x0000, Name: INT_STATUS

The interrupt status register indicates which events capable of generating an interrupt have occurred. Write a 1 to the desired bit position

to acknowledge the event and then clear the bit. This register can be written while the device is locked.
