Description

TEMP_FAULT

read-write

Status flag indicating an over temperature condition has

occurred since last clear. Temperature threshold is set by

ADC_LIMITS.ADC_T_LIM. This flag requires

ADC_CC_CTRL.ADC_INTERVAL be set to a non-zero

value to ensure automatic periodic ADC readings are tak-

en.

Note this flag is masked by default - set corresponding bit

in the STATUS_GM register to unmask.

Can be cleared by writing a "1".

I2C_FAULT

read-write

Status flag indicating an I2C fault has occurred since last

clear.

Note this flag is masked by default - set corresponding bit

in the STATUS_GM register to unmask.

Can be cleared by writing a "1".

OTP_CRC_FAULT

read-write

Status flag indicating an OTP CRC violation has occurred

since last clear.

Note this flag is masked by default - set corresponding bit

in the STATUS_GM register to unmask.

Can be cleared by writing a "1".

OTP_READ

read-write

Status flag indicating that OTP was read since last clear.

This flag is expected to be set everytime the EFP01 is

powered up, and should be cleared at power-up.

It is recommended to keep this flag unmasked always to

ensure that any EFP01 reset will result in an IRQ to the

host MCU, allowing the host MCU to reinitialize any

EFP01 registers.

Note this flag is unmasked by default - therefore, every

power-up and reset deassertion (which causes an OTP

read), results in an unmasked flag and the IRQ pin asser-

tion.

Can be cleared by writing a "1".
