13 / 51 page  MSP430FE42xA MIXED SIGNAL MICROCONTROLLER SLAS588 -- FEBRUARY 2008 13 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 WDT+ watchdog timer The primary function of the watchdog timer (WDT+) module is to perform a controlled system restart after a software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed in an application, the module can be configured as an interval timer and can generate interrupts at selected time intervals. Timer_A3 Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers. TIMER_A3 SIGNAL CONNECTIONS INPUT PIN NUMBER DEVICE INPUT SIGNAL MODULE INPUT NAME MODULE BLOCK MODULE OUTPUT SIGNAL OUTPUT PIN NUMBER 48 - P1.5 TACLK TACLK ACLK ACLK Timer NA SMCLK SMCLK Timer NA 48 - P1.5 TACLK INCLK 53 - P1.0 TA0 CCI0A 53 - P1.0 52 - P1.1 TA0 CCI0B CCR0 TA0 DVSS GND CCR0 TA0 DVCC VCC 51 - P1.2 TA1 CCI1A 51 - P1.2 51 - P1.2 TA1 CCI1B CCR1 TA1 DVSS GND CCR1 TA1 DVCC VCC 45 - P2.0 TA2 CCI2A 45 - P2.0 ACLK (internal) CCI2B CCR2 TA2 DVSS GND CCR2 TA2 DVCC VCC universal synchronous/asynchronous receive transmit (USART) The MSP430FE42xA devices have one hardware USART peripheral module (USART0) that is used for serial data communication. The USART supports synchronous SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered transmit and receive channels. ESP430CE1A The ESP430CE1A module integrates a hardware multiplier, three independent 16-bit sigma-delta A/D converters (SD16) and an embedded signal processor (ESP430). The ESP430CE1A module measures 2-wire or 3-wire single-phase energy and automatically calculates parameters that are made available to the MSP430 CPU. The module can be calibrated and initialized to accurately calculate energy, power factor, etc., for a wide range of metering sensor configurations. |
