ALM[0]
Deactive
R/TOW⁽¹⁾
ALM[0] Deactive Interrupt. This signal indicates that the falling edge of the
ALM[0] (ALM[0] indicates the user temperature range violation) signal is
’0’
detected. It is cleared by writing ’1’ to this bit position.
Note that the "ALM[0] Deactive" signal is generated locally from the core.
This signal indicates that the SYSMON macro has deactivated the user
temperature violation signal output.
23
OT
Deactive
R/TOW⁽¹⁾
OT Deactive Interrupt. This signal indicates that the falling edge of the Over
Temperature signal is detected. It is cleared by writing ’1’ to this bit position.
’0’ _{Note that the "OT Deactive" signal is generated locally from the core. This}
signal indicates that the SYSMON macro has deactivated the Over
Temperature signal output.
24
JTAG
MODIFIED
R/TOW⁽¹⁾⁽²⁾
’0’
JTAGMODIFIED Interrupt. This signal indicates that a write to DRP through
JTAG interface has occurred. It is cleared by writing ’1’ to this bit position.
25
JTAG
LOCKED
R/TOW⁽¹⁾⁽²⁾
’0’
JTAGLOCKED Interrupt. This signal is used to indicate that a DRP port lock
request has been made by the Joint Test Action Group (JTAG) interface.
End of Conversion signal Interrupt. This signal transitions to an active High
26
EOC
R/TOW⁽¹⁾⁽²⁾
N/A at the end of an ADC conversion when the measurement is written to the
SYSMON hard macro’s status register.
End of Sequence Interrupt. This signal transitions to an active High when
27
EOS
R/TOW⁽¹⁾⁽²⁾
N/A the measurement data from the last channel in the auto sequence is written
to the status registers.
System Monitor VCCAUX-sensor Interrupt. System Monitor
28
ALM[2]
R/TOW⁽¹⁾⁽²⁾
’0’ VCCAUX-sensor alarm output interrupt occurs when VCCAUX exceeds
user defined threshold.
System Monitor VCCINT-sensor Interrupt. System Monitor VCCINT-sensor
29
ALM[1]
R/TOW⁽¹⁾⁽²⁾
’0’ alarm output interrupt occurs when VCCINT exceeds user defined
threshold.
System Monitor temperature-sensor Interrupt. System Monitor
30
ALM[0]
R/TOW⁽¹⁾⁽²⁾
’0’ temperature-sensor alarm output interrupt occurs when device temperature
exceeds user defined threshold.
Over-Temperature alarm Interrupt. Over-Temperature alarm output
31
OT
R/TOW⁽¹⁾⁽²⁾
’0’ interrupt occurs when the die temperature exceeds a factory set limit of 125
degree celsius.
Notes:
1. TOW = Toggle On Write. Writing a ’1’ to a bit position within the register causes the corresponding bit position in the register to
toggle.
2. This interrupt signal is directly generated from the SYSMON hard macro.
