Table 35-3. Signal properties in automatic noise operation mode (continued)
Name Function I/O type Power Up/Reset state
DVOLT[1:0] Selects voltage rails of the
internal oscillator I 00
MODE[3:0] DVOLT counter bits output.
This field keeps 0000b if
MODE[3:2] is not 11 after
entering automatic noise
mode.
O 0000
35.4.13.2 Single threshold noise modes
These modes are reset by MODE[3:2]=01 and 10.
In this mode, the thresholds are set by user via register bits as described in the following
table.
During this mode the internal oscillator rails are set to the maximum (equivalent to
DVOLT[1:0]=00).
Table 35-4. Signal properties in single noise modes (1,2)
Name Function I/O type Power up /
reset
MODE[3:2] 01 or 10- Single thrshold noise mode operation. I 00
DVOLT[1:0],
EXTCHRG[2:1] In this operation mode these 4 bits are used select the noise
threshold. These combinations are the maximum possible
combinations, however, in real application, only the valid
combinations in the above table should be used.
