Description
Writing a “1” to this bit causes the R_RST output to be pulsed low for a
minimum of 125 ms. This bit will self-clear to 0 when the R_RST pulse is
complete. Writing a “0” to this bit has no effect. Reading this bit reflects the
state of this register bit and not the state of the pin. The power-on default
value is “0.”
Writing a “1” to this bit causes the R_OFF output to be driven high. This bit
will be cleared, and the output driven low, when RST is asserted. Writing a
“0” to this bit has no effect. The power-on default value is “0.”

Description
A one indicates that the external thermal overload limit is currently exceeded.
This bit represents the logic level of the GPI pin if Bit 6 of the Configuration
Register is “0,” or the inverse logic level of the GPI pin if Bit 6 of the Con-
figuration Register is “1.”
A one indicates that the internal thermal overload limit is currently exceeded.
