		u_int32_t	sis3820_base,
		int	mode,
		int	nwords,
		u_int32_t *	data
	)

Readout of SIS3820 in different modes. Scaler counts are automatically cleared after each read operation if non-clearing mode in SIS3820_OPERATION_MODE is set to 0 (default value).

Return:

0 if everything went smooth

error flag from ioctl or -1 if number of requested words is different to number of words read

Parameters

device	is the is the handle to the VME-PCI device
sis3820_base	is the SIS3820 VME address
mode	defines read out mode: possible values are A32BLT32 and for MCS operation: A32MBLT64 or A32_2eVME; a A32BLT32
nwords	number of words to be read
data	array where scaler data are written
