APB ComponentsWatchdog Integration Test Control RegisterThe WDOGITCR Register is read/write. It is a single-bit register that enablesintegration test mode. When in this mode, the masked interrupt output, WDOGINT,and reset output, WDOGRES, are directly controlled by the test output set register.Figure 4-11 shows the register bit assignments.31 1 0UndefinedIntegration Test Mode EnableTable 4-18 lists the register bit assignments.Figure 4-11 WDOGITCR Register bit assignmentsTable 4-18 WDOGITCR Register bit assignmentsBits Name Function[31:1] - Reserved, read undefined, must read as zeros[0] Integration Test Mode Enable When set HIGH, places the Watchdog into integration test modeWatchdog Integration Test Output Set RegisterThe WDOGITOP Register is write-only. When in integration test mode, the enabledinterrupt output and reset output are driven directly from the values in this register.Figure 4-12 shows the register bit assignments.31 2 1 0UndefinedIntegration Test WDOGINT valueIntegration Test WDOGRES valueFigure 4-12 WDOGITOP Register bit assignments4-18 Copyright © 2003, 2007 ARM Limited.
