State diagram terms and descriptions

Term

Description

KEY

Key on detection, see Chapter 4.3

ON: high voltage level at pin KEY

OFF: low voltage level at pin KEY

V5VIUV

5 V undervoltage detection at pin V5VI

Diag0.V5VIUV = 0: voltage in operational range

Diag0.V5VIUV = 1: undervoltage at pin V5VI

Afterrun setting

Config.AE = 0: afterrun disabled

Config.AE = 1: afterrun enabled

NRIO

logic status of NRIO pin

NRIO = 0: logic low level

NRIO = 1: logic high level

Write WD register

SPI write access to watchdog register

Watchdog reset

see Chapter 4.2.4

Error

watchdog reset OR Diag0.V5VIUV = 1 (boolean OR)

No error

no watchdog reset AND Diag0.V5VIUV = 0 (boolean AND)
