Description
Reload value to get a 10 millisecond System Tick underflow rate when running
at 100 MHz. This value initialized at reset with a factory supplied value selected
for the LPC17xx. The provided values of TENMS, SKEW, and NOREF are
applicable only when using a CPU clock or external STCLK source of 100 MHz.
Reserved, user software should not write ones to reserved bits. The value read
from a reserved bit is not defined.
Indicates whether the TENMS value will generate a precise 10 millisecond time,
or an approximation. This bit is initialized at reset with a factory supplied value
selected for the LPC17xx. See the description of TENMS above.
When 0, the value of TENMS is considered to be precise. When 1, the value of
TENMS is not considered to be precise.
Indicates whether an external reference clock is available. This bit is initialized
at reset with a factory supplied value selected for the LPC17xx. See the
description of TENMS above.
When 0, a separate reference clock is available. When 1, a separate reference
clock is not available.
