Page 10: Msc1211 Description
C interface, a 16-bit PWM output, data flash memory, 1,280 bytes of data RAM, dual UARTS, and dual DPTR registers. The MSC1211 has an enhanced 8051 core that only requires 4 clock cycles per machine cycle. It has extra timers, watchdog, brownout and low-voltage detect circuits, power management control and hardware breakpoint registers. -
Page 11: Analog Inputs
A prototyping area is provided on the MSC1211EVM. This may be used to in- corporate additional circuitry, such as special reference or conditioning cir- cuits, into the system. All of the signals on the MSC1211 are brought to con- nector pads. Additionally, there are digital and analog power and ground holes in the prototyping area. -

Page 20: Switches
RESET Switch Switch SW1 is a miniature pushbutton that, when pressed, forces the MSC1211 RST line high. When released, the MSC1211 enters a reset cycle. If communication becomes disrupted between the host and the board, or the board is unresponsive, pressing RESET will return the system to normal op- eration. -
