Counter Constant A Register (Read/Write)
Note that the Counter Constant
Registers are cleared (set to 0)
following a system or software
reset.
This read/write register is used to store the counter/timer constant A value
(initial value) for the various counting modes. It is necessary to load the
constant value into the counter in one clock cycle. Thus, access to this
register is allowed on a 32-bit basis, only.
The contents of the Counter Constant A and Counter Constant A Register 2
can be toggled for the counter/timers. Writing a “1” to the counter’s
corresponding toggle counter constants bit will cause the counter to use the
values in Counter Constant A Regis
ter 2. Writing a “0” will cause the
counter to use the values in Counter Constant A. By default, a counter will
always use the values in Counter Constant A Register.
Counter Constant A Register 2 (Read/Write)
Note that the Counter Constant
Registers are cleared (set to 0)
following a system or software
reset.
This read/write register is used to store the counter/timer constant A
register 2 value (initial value) for the various counting modes. It is necessary
to load the constant value into the counter in one clock cycle. Thus, access
to this register is allowed on a 32-bit basis, only.
The contents of the Counter Constant A and Counter Constant A Register 2
can be toggled for the counter/timers. Writing a “1” to the counter’s
corresponding toggle counter constants bit will cause the counter to use the
values in Counter Constant A Register 2. Writing a “0” will cause the
counter to use the values in Counter Constant A. By default, a counter will
always use the values in Counter Constant A Register.
Counter Constant B Register (Read/Write)
Note that the Counter Constant
Registers are cleared (set to 0)
following a system or software
reset.
This read/write register is used to store the counter/timer constant B value
(initial value) for the various counting modes. It is necessary to load the
constant value into the counter in one clock cycle. Thus, access to this
register is allowed on a 32-bit basis, only.
The contents of the Counter Constant B and Counter Constant B Register 2
can be togg
led for the counter/timers. Writing a “1” to the counter’s
corresponding toggle counter constants bit will cause the counter to use the
values in Counter Constant B Register 2. Writing a “0” will cause the counter
to use the values in Counter Constant B. By default, a counter will always
use the values in Counter Constant B Register.
Counter Constant B Register 2 (Read/Write)
