Table 18. Event Timing 2 Register (continued)
BIT NAME DESCRIPTION
6:5 TP[1:0]
Temperature Port: These bits set the number of temperature ports to stimulate during a
temperature measurement sequence and the sequence in which the temperature ports are
stimulated.
TP1 TP0 DESCRIPTION
0 0 Measure ports T1 and T3
0 1 Measure ports T2 and T4
1 0 Measure ports T1, T3, and T2
1 1 Measure ports T1, T3, T2, and T4
4:2 PRECYC[2:0]
Preamble Temperature Cycle: These 3 bits are used to set the number of cycles to use as
preamble for reducing dielectric absorption of the temperature measurement capacitor. Each cycle
comprises one temperature measurement sequence as dened by the TP[1:0] bits.
PRECYC2 PRECYC1 PRECYC0 DESCRIPTION
0 0 0 0 dummy cycle
0 0 1 1 dummy cycles
0 1 0 2 dummy cycles
0 1 1 3 dummy cycles
1 0 0 4 dummy cycles
1 0 1 5 dummy cycles
1 1 0 6 dummy cycles
1 1 1 7 dummy cycles
1:0 PORTCYC[1:0]
Port Cycle Time: These two bits dene the time interval between successive individual
temperature port measurements. It is a start-to-start time. These bits also dene the timeout
function of the temperature measurement ports. See the Temperature Operation section for timeout
details.
PORTCYC1 PORTCYC0 DESCRIPTION (µs)
0 0 128
0 1 256
1 0 384
1 1 512
