VT_APS_NTIME[3:0]
APS NTIME Detection Control.
This nibble is programmed
to provision the number of consecutive consistent new values
required to accept a new VT_APS[1—28][3:0] (
Table 191 on
page 163
).
Note:
The valid range of values is 0x1—0xF. A value of 0x0
will be mapped to 0x1.
VT Signal Label NTIME Detection Control.
This nibble is
programmed to provision the number of consecutive consis-
tent new values required to accept a new
VT_LAB[1—28][2:0] (
Table 190 on page 163
).
