Type Description
rw Timer T13 Input Clock Select
Selects the input clock for timer T13 which is derived
from the peripheral clock according to the equation
f_T13 = f_per / 2^<T13CLK>.
000 f_T13 = f_per
001 f_T13 = f_per / 2
010 f_T13 = f_per / 4
011 f_T13 = f_per / 8
100 f_T13 = f_per / 16
101 f_T13 = f_per / 32
110 f_T13 = f_per / 64
111 f_T13 = f_per / 128
rw Timer T13 Prescaler Bit
In order to support higher clock frequencies, an
additional prescaler factor of 1/256 can be enabled for
the prescaler for T13.
0 The additional prescaler for T13 is disabled.
1 The additional prescaler for T13 is enabled.
rh Timer T13 Run Bit
T13R starts and stops timer T13. It is set/reset by SW
by setting bits T13RR orT13RS or it is set/reset by HW
according to the function defined by bitfields T13SSC,
T13TEC and T13TED.
0 Timer T13 is stopped.
1 Timer T13 is running.
