Local Diode Overtemperature Limit Register (TLOCOTL)

This register holds the limit value used for overtemperature detection. TLOCOTL is set to 7F16 on reset.

Location: 00 FF2816

Type: R/W

ADC Parameters Index Register (ADCPINX)

This register holds an index to the ADC parameters registers. Use it while initializing the ADC (see “Initializing the ADC” on

page 174 for more details). ADCPINX is cleared (0016) on reset.

Location: 00 FF2A16

Type: R/W

ADC Parameters Data Register (ADCPD)

This register enables access to the ADC parameters registers. Use it while initializing the ADC (see “Initializing the ADC” on

page 174 for more details).

Location: 00 FF2C16

Type: R/W

Description

7-0

OTSLIM (Overtemperature Limit Value). Threshold value for Overtemperature Event detection. Whenever the

temperature measured by the local (internal) diode exceeds this limit, the OTSEV bit is set, an interrupt is sent

to the core (if INTOTEN in ADCCNF register is set to 1) and the OTS signal becomes active. To calculate the

required value for a speciﬁc temperature limit, see Section 4.11.4 on page 173.

Range:

−128 to +127 (default is +127; these are decimal values); 8-bit, 2s complement value with 1 LSB = 1oC.

Description

15-0 Parameter Data. The register is used to access the ADC parameters register that the Index register (ADCPINX)

points to.

Writing 0116 to index 0016 locks the parameter data registers from any further writes until the next reset.
