The behavior of UART register of Chorus 4M

[M. Tsutsumi]

Hi,

 I checked UART register of Chorus 4M my environment.

If I would like to set AUTOWU bit in LINCR1 register, is following sequence right?

linflexlp->LINCR1.R = 1; /* enter INIT mode */

linflexlp->LINCR1.R = 0x1001; /* set AUTOWU */

linflexlp->LINCR1.R = 0x1000; /* exit INIT mode */

When I wite '0' (0x00000000) to LINCR1 register to exit INIT mode like serial_lld.c in SPC5Studio (following), not only INIT bit but also other bits on LINCR1 register is clear. Is it right?

/* Leaves the configuration mode.*/

linflexlp->LINCR1.R = 0;

If it is right, I think it is very important behavior.

Best Regards,

Hi Tsutsumi-sun,

your sequence of instructions is correct. You can also use the following sequence:

SD1.linflexlp->LINCR1.B.INIT = 1; /* enter INIT mode */

SD1.linflexlp->LINCR1.B.AWUM = 1; /* set AUTOWU */

SD1.linflexlp->LINCR1.B.INIT = 0; /* exit INIT mode */
