channels

 Mask function and tri-state output for each PWM channel

 Able to trigger EADC to start conversion

Watchdog

 18-bit free running up counter for WDT time-out interval

 Supports multiple clock sources from LIRC (default selection),

HCLK/2048 and LXT with 8 selectable time-out period

 Able to wake up system from Power-down or Idle mode

 Time-out event to trigger interrupt or reset system

 Supports four WDT reset delay periods, including 1026, 130, 18 or 3

WDT_CLK reset delay period

 Configured to force WDT enabled on chip power-on or reset

Window Watchdog

 Clock sourced from HCLK/2048 or LIRC; the window set by 6-bit

down counter with 11-bit prescale

 Suspended in Idle/Power-down mode

Analog Interfaces

Enhanced Analog-to-Digital

Converter (EADC)

 One 12-bit, 19-ch 3.43 MSPS SAR EADC with up to 16 single-

ended input channels or 8 differential input pairs; 10-bit accuracy is

guaranteed.

 Three internal channels for V

BAT, band-gap VBG input and

Temperature sensor input.

 Supports external V

REF pin or internal reference voltage VREF: 1.6V,

2.0V, 2.5V, and 3.0V.

 Two power saving modes: Power-down mode and Standby mode.

 Supports calibration capability.

 Analog-to-Digital conversion can be triggered by software enable,

external pin, Timer 0~3 overflow pulse trigger or EPWM trigger.
