32-Bit Watchdog Timer General Overview

Watchdog Module Under Emulation

Watchdog Timer Registers

WD_SYSCONFIG

WD_SYSSTATUS

To keep mapping compatibility between 32-bit watchdog and dual-mode timer modules.

During emulation mode, the 32-bit watchdog can/cannot continue to run

according to the value of the EMUFREE bit of the system configuration register

(WD_SYSCONFIG).

If EMUFREE is 1, timer execution is not stopped in emulation mode and a reset

pulse is still generated when overflow is reached.

If EMUFREE is 0, counters (prescaler/timer) are frozen and increment starts

again after exit from emulation mode.

Address of register: Start address + Address offset

Registers width: 32 bits (can be accessed as 32 bits or as 2 x 16 bits –

Table 5 lists the 32-bit watchdog timer registers. Table 6 through Table 14

describe the register bits.
