DSCCB

Structure containing hardware settings for the current board. Some elements are unique to particular boards.

Structure Members

Name	Description
boardtype	The board type constant; automatically filled by dscInitBoard;
boardnum	The handle to the board; automatically filled in by dscInitBoard
base_address	Base address of the board; refer to the board's user manual for valid base address settings
int_level	Interrupt level of the board; used for boards with only one IRQ.
RMM_external_trigger	Enable or disable the external trigger; Used only on RMM416 and RMM1612
RMM_external_trigger_c3	Enable or disable the external trigger; RMM416- and RMM1612-specific
EMM_IOAddr[8]	I/O addresses for up to eight ports; EMM8-specific
EMM_Interrupt[8]	Interrupts for up to eight ports; EMM8-specific
clkfrq0	Frequency for on-board counter 0; used only on Prometheus; 0 = 10 MHz, 1= 1 MHz;
clkfrq1	Frequency for on-board counter 1; used only on Prometheus; 0 = 10 MHz, 1= 100KHz;
clksel1	0 = internal oscillator with frequency set by clkfrq1, 1= external clock input CLK1; used only on Prometheus
address_space	Size of I/O block in bytes to allocate. Only needed for DSC_RAW board type.
