CMSIS LPC540xx.h

danielgull — Mon, 23 Mar 2020 11:35:35 GMT

In the CMSIS header file of

SDK_2.7.0_LPCXpresso54018\devices\LPC54018\LPC54018.h

the entry

SYSCON_EMCDYCTRL_CMD_DELAY_...

is not identical to the entry in the file

SDK_2.7.0_LPC54628J512\devices\LPC54628\LPC54628.h

here the entry contains an additional "L" in the name i.e. "DLY"

SYSCON_EMCDLYCTRL_CMD_DELAY_...

Can these CMSIS files be streamlined / harmonized in the next SDK release?

Many thanks

Dani

Hi, Daniel,

I see your question, the terminology of the same register bits are defined differently in different file, so I think it is a typo, but it does not take effect on the code execution.

Anyway, I will tell the firmware team of the issue.

Thank you for pointing the issue.

FOR LPC54628.h, they are defgined as following:

/*! @name EMCDLYCTRL - EMC clock delay control */
/*! @{ */
#define SYSCON_EMCDLYCTRL_CMD_DELAY_MASK         (0x1FU)
#define SYSCON_EMCDLYCTRL_CMD_DELAY_SHIFT        (0U)
#define SYSCON_EMCDLYCTRL_CMD_DELAY(x)           (((uint32_t)(((uint32_t)(x)) << SYSCON_EMCDLYCTRL_CMD_DELAY_SHIFT)) & SYSCON_EMCDLYCTRL_CMD_DELAY_MASK)
#define SYSCON_EMCDLYCTRL_FBCLK_DELAY_MASK       (0x1F00U)
#define SYSCON_EMCDLYCTRL_FBCLK_DELAY_SHIFT      (8U)
#define SYSCON_EMCDLYCTRL_FBCLK_DELAY(x)         (((uint32_t)(((uint32_t)(x)) << SYSCON_EMCDLYCTRL_FBCLK_DELAY_SHIFT)) & SYSCON_EMCDLYCTRL_FBCLK_DELAY_MASK)
/*! @} */

For LPC54018.h or lpc54s018.h, they are defined as following, the L is missing for unknown reason.
/*! @name EMCDYCTRL - EMC clock delay control */
/*! @{ */
#define SYSCON_EMCDYCTRL_CMD_DELAY_MASK          (0x1FU)
#define SYSCON_EMCDYCTRL_CMD_DELAY_SHIFT         (0U)
#define SYSCON_EMCDYCTRL_CMD_DELAY(x)            (((uint32_t)(((uint32_t)(x)) << SYSCON_EMCDYCTRL_CMD_DELAY_SHIFT)) & SYSCON_EMCDYCTRL_CMD_DELAY_MASK)
#define SYSCON_EMCDYCTRL_FBCLK_DELAY_MASK        (0x1F00U)
#define SYSCON_EMCDYCTRL_FBCLK_DELAY_SHIFT       (8U)
#define SYSCON_EMCDYCTRL_FBCLK_DELAY(x)          (((uint32_t)(((uint32_t)(x)) << SYSCON_EMCDYCTRL_FBCLK_DELAY_SHIFT)) & SYSCON_EMCDYCTRL_FBCLK_DELAY_MASK)
