Detailed Description

Function Documentation

DDL_WWDT_Enable()

__STATIC_INLINE void DDL_WWDT_Enable

(

WWDT_TypeDef *

WWDTx

)

Enable Window Watchdog. The watchdog is always disabled after a reset.

Note

It is enabled by setting the WDGA bit in the WWDT_CTRL register, then it cannot be disabled again except by a reset. This bit is set by software and only cleared by hardware after a reset. When WDGA = 1, the watchdog can generate a reset.

Parameters

WWDTx

WWDT Instance

Return values

None

DDL_WWDT_GetCounter()

__STATIC_INLINE uint32_t DDL_WWDT_GetCounter

(

WWDT_TypeDef *

WWDTx

)

Return current Watchdog Counter Value (7 bits counter value).

Parameters

WWDTx

WWDT Instance

Return values

7	bit Watchdog Counter value

Definition at line 181 of file g32r4xx_ddl_wwdt.h.

DDL_WWDT_GetPrescaler()

__STATIC_INLINE uint32_t DDL_WWDT_GetPrescaler

(

WWDT_TypeDef *

WWDTx

)

Return current Watchdog Prescaler Value.

Parameters

WWDTx

WWDT Instance

Return values

Returned

value can be one of the following values: DDL_WWDT_PRESCALER_1 DDL_WWDT_PRESCALER_2 DDL_WWDT_PRESCALER_4 DDL_WWDT_PRESCALER_8

DDL_WWDT_GetWindow()

__STATIC_INLINE uint32_t DDL_WWDT_GetWindow

(

WWDT_TypeDef *

WWDTx

)

Return current Watchdog Window Value (7 bits value).

Parameters

WWDTx

WWDT Instance

Return values

7	bit Watchdog Window value

Definition at line 242 of file g32r4xx_ddl_wwdt.h.

DDL_WWDT_IsEnabled()

__STATIC_INLINE uint32_t DDL_WWDT_IsEnabled

(

WWDT_TypeDef *

WWDTx

)

Checks if Window Watchdog is enabled.

Parameters

WWDTx

WWDT Instance

Return values

State

of bit (1 or 0).

DDL_WWDT_SetCounter()

__STATIC_INLINE void DDL_WWDT_SetCounter	(	WWDT_TypeDef *	WWDTx,
		uint32_t	Counter )

Set the Watchdog counter value to provided value (7-bits T[6:0]).

Note

When writing to the WWDT_CTRL register, always write 1 in the MSB b6 to avoid generating an immediate reset This counter is decremented every (4096 x 2expWDGTB) PCLK cycles A reset is produced when it rolls over from 0x40 to 0x3F (bit T6 becomes cleared) Setting the counter lower then 0x40 causes an immediate reset (if WWDT enabled)

Parameters

WWDTx	WWDT Instance
Counter	0..0x7F (7 bit counter value)

Return values

None

Definition at line 171 of file g32r4xx_ddl_wwdt.h.

DDL_WWDT_SetPrescaler()

__STATIC_INLINE void DDL_WWDT_SetPrescaler	(	WWDT_TypeDef *	WWDTx,
		uint32_t	Prescaler )

Set the time base of the prescaler (WDGTB).

Note

Prescaler is used to apply ratio on PCLK clock, so that Watchdog counter is decremented every (4096 x 2expWDGTB) PCLK cycles

Parameters

WWDTx	WWDT Instance
Prescaler	This parameter can be one of the following values: DDL_WWDT_PRESCALER_1 DDL_WWDT_PRESCALER_2 DDL_WWDT_PRESCALER_4 DDL_WWDT_PRESCALER_8

Return values

None

Definition at line 198 of file g32r4xx_ddl_wwdt.h.

DDL_WWDT_SetWindow()

__STATIC_INLINE void DDL_WWDT_SetWindow	(	WWDT_TypeDef *	WWDTx,
		uint32_t	Window )

Set the Watchdog Window value to be compared to the downcounter (7-bits W[6:0]).

Note

This window value defines when write in the WWDT_CTRL register to program Watchdog counter is allowed. Watchdog counter value update must occur only when the counter value is lower than the Watchdog window register value. Otherwise, a MCU reset is generated if the 7-bit Watchdog counter value (in the control register) is refreshed before the downcounter has reached the watchdog window register value. Physically is possible to set the Window lower then 0x40 but it is not recommended. To generate an immediate reset, it is possible to set the Counter lower than 0x40.

Parameters

WWDTx	WWDT Instance
Window	0x00..0x7F (7 bit Window value)

Return values

None
