Watchdog
Enable the watchdog timer by writing a 1 to the WDE
bit in the CLK_CTRL register. After enabling the watch-
dog timer, the device asserts
RESET for 250ms, if the
watchdog address register is not written every 500ms.
Due to the asynchronous nature of the watchdog timer,
the watchdog timeout period varies between 500ms
and 750ms. Write a 0 to the WDE bit to disable the
watchdog timer. See Figure 11 for a block diagram of
the watchdog timer.
High-Frequency Clock
An internal oscillator and a frequency-locked loop (FLL)
are used to generate a 4.9152MHz ±1% high-frequen-
cy clock. This clock and derivatives are used internally
by the ADC, analog switches, and PWM. This clock sig-
nal outputs to CLK. When the FLL is enabled, the high-
frequency clock is locked to the 32.768kHz reference.
If the FLL is disabled, the high-frequency clock is free-
running. At power-up, the CLK pin defaults to a
2.4576MHz clock output, which is compatible with most
Cs. See Figure 12 for a block diagram of the high-fre-
quency clock.
User-Programmable I/Os
The MAX11359A provides four digital programmable
I/Os (UPIO1–UPIO4). Configure UPIOs as logic inputs
or outputs using the UPIO control register. Configure
the internal pullups using the UPIO setup register, if
required. At power-up, the UPIOs are internally pulled
up to DVDD. UPIO_ outputs can be referenced to
DVDD or CPOUT. See the
UPIO__CTRL Register and
UPIO_SPI Register sections for more details on config-
uring the UPIO_ pins.
