6.13 Peripheral subsystem
6.13.1
Peripheral subsystem clock description
The peripheral subsystem is clocked by a number of different clocks:
CLK_SYS_PESS
CLK_UART0/1
CLK_SPI0/1/2
CLK_TMR0/1/2/3
CLK_SAFE see
Section 6.7.2
6.13.2
Watchdog timer
The purpose of the watchdog timer is to reset the ARM9 processor within a reasonable
amount of time if the processor enters an error state. The watchdog generates a system
reset if the user program fails to trigger it correctly within a predetermined amount of time.
Key features:
Internal chip reset if not periodically triggered
Timer counter register runs on always-on safe clock
Optional interrupt generation on watchdog time-out
Event-router pin connections
