(1) Some signals listed are virtual functions that present alternate multiplexing options. These virtual functions are controlled via
CTRL_CORE_ALT_SELECT_MUX or CTRL_CORE_VIP_MUX_SELECT registers. For more information on how to use these options,
please refer to Device TRM, Chapter Control Module, Section Pad Configuration Registers.
5.9.6.9 Timers
The device has 16 general-purpose (GP) timers (TIMER1 - TIMER16), two watchdog timers, and a 32-kHz
synchronized timer (COUNTER_32K) that have the following features:
• Dedicated input trigger for capture mode and dedicated output trigger/pulse width modulation (PWM)
signal
• Interrupts generated on overflow, compare, and capture
• Free-running 32-bit upward counter
• Supported modes:
– Compare and capture modes
– Auto-reload mode
– Start-stop mode
• On-the-fly read/write register (while counting)
The device has two system watchdog timer (WD_TIMER1 and WD_TIMER2) that have the following
features:
• Free-running 32-bit upward counter
• On-the-fly read/write register (while counting)
• Reset upon occurrence of a timer overflow condition
The device includes one instance of the 32-bit watchdog timer: WD_TIMER2, also called the MPU
watchdog timer.
The watchdog timer is used to provide a recovery mechanism for the device in the event of a fault
condition, such as a non-exiting code loop.
In are presented the specific groupings of signals (IOSET) for use with TIMERS.
NOTE
For additional information on the Timer Module, see the Device TRM.
5.9.6.10 I2C
The device includes 6 inter-integrated circuit (I2C) modules which provide an interface to other devices
compliant with Philips Semiconductors Inter-IC bus (I2C-bus™) specification version 2.1. External
components attached to this 2-wire serial bus can transmit/receive 8-bit data to/from the device through
the I2C module.
NOTE
Note that, on I2C1 and I2C2, due to characteristics of the open drain IO cells, HS mode is
not supported.
NOTE
Inter-integrated circuit i (i=1 to 6) module is also referred to as I2Ci.
