EXAMPLE 6:

Data writes to the I2CTRN Special Function
Register may not be correct at device operation
greater than 20 MIPS for V
to 5.5V (or 10 MIPS V
3.6V).
If the dsPIC DSC device needs to operate at a
throughput higher than 20 MIPS, the user should
incorporate the suggested work around while
writing to the I2CTRN SFR.
Applications that use I
Microchip’s dsPIC30F Peripheral Library should
operate the device at 20 MIPS or less.
Work arounds
Work around 1: For Assembly Language
Source Code
When writing to the I2CTRN SFR, the user must
follow the write sequence shown in
this example, a Memory Direct Addressing mode
is used to write to the SFR. The application may
use any addressing mode to perform the write
operation. Note that interrupts must be temporarily
disabled as shown, so that this write sequence
does not get interrupted.

Work around 2: For C Language Source Code
For C programmers, the MPLAB C30 v1.30
toolsuite provides a built-in function that may be
incorporated in the application source code. This
function may be used to write to the I2CTRN SFR.
Some examples of usage are shown in the
“readme.txt” file provided with the MPLAB C30
v1.30 toolsuite. The function has the following
prototype:
void __builtin_writesfr(volatile void *,
unsigned int);
The special argument is the address of a 16-bit
SFR (I2CTRN in this case). For example, the
I2CTRN register can be written using a function
call:
__builtin_writesfr(&I2CTRN, reg_value);
where ‘reg_value’ is the 16-bit value to be
written to the SFR.
