Internal Temperature Data Register (Read)
BIT
FIELD NAME
DESCRIPTION
Internal temperature measurement data
11:0 TMPINTDAT[11:0] • Temperature measurement produced by the internal temperature sensor.
• The data sample is represented in two’s complement, and one LSB represents 0.125°C.
1st External Temperature Data Register (Read)
BIT
FIELD NAME
DESCRIPTION
1st external temperature measurement data
11:0 TMPEXT1DAT[11:0] • Temperature measurement produced by the first external temperature sensor.
• The data sample is represented in two’s complement, and one LSB represents 0.125°C.
2nd External Temperature Data Register (Read)
BIT
FIELD NAME
DESCRIPTION
2nd external temperature measurement data
11:0
TMPEXT2DAT[11:0] ^{• Temperature measurement produced by the second external temperature sensor.}
• The data sample is represented in two’s complement, and one LSB represents 0.125°C.

FIELD NAME
GPIST[5:0]
GPIST[10:6]
GPIST[11]
DESCRIPTION
Status of GPI event detection for ports 0 to 11
• Asserted when an event is detected on a GPI-configured port. The type of event to detect is
set by the corresponding GPI IRQ register.
• Once a GPIDT interrupt is generated, the host can identify which GPI port(s) caused the
interrupt by reading GPIST[10:0] and GPIST[11] registers.
• GPIST content is not affected by any related interrupt mask. Activity on GPI-configured
ports is recorded by GPIST regardless of the mask interrupt register setting.
• Cleared after the interrupt register is read, and after both GPIST[10:0] and GPIST[11]
registers are read, subsequently.
