Page 40: Control And Status Register Bit Definitions
VMIVME-1129 128-bit Digital Input Board with Built-In-Test Control and Status Register Bit Definitions The Control and Status Register (CSR) is a 16-bit register that is used to control the board's Fail LED and the test registers' outputs. Table 3-3 shows the bits used to perform these functions. -
Page 41: Input Registers Bit Definitions
Input Registers Bit Definitions Input Registers Bit Definitions The following table (Table 4.4-1) lists the input channels and their associated register bit locations. The internal data bit can be used as a guide to locate an input channel when you are doing a longword transfer. When doing word or byte transfers the even address bytes will go to bits 15 through 8 on the VMEbus data bus while the odd address bytes go to bits 7 through 0. - Page 42 VMIVME-1129 128-bit Digital Input Board with Built-In-Test Table 3-4 Input Data Registers Bit Map (Continued) XXX1 1000 DATA REGISTER 4 UPPER BYTE (Read /Write) Bit 31 Bit 30 Bit 29 Bit 28 Bit 27 Bit 26 Bit 25 Bit 24...

Built-In-Test Programming Built-In-Test Programming Built-in-test is activated when either or both test mode bits in the CSR are cleared. When test mode is active, data written to a data register will overwrite the external inputs. Then when the same register is read, the data stored in the test register should be read. - Page 44 VMIVME-1129 128-bit Digital Input Board with Built-In-Test...
