Command Register (0x22, 0x4A, 0x72, 0x9A, 0xC2, 0xEA) — Read and Write

 

 

Command Register - Writing to this register instructs the

 

 

microprocessor to perform the specified function. If this command

D15 – D0

CMD15 – 0

performs a calculation, the data is returned into the corresponding result

register.

 

 

For a detailed description of the commands, refer to the Microprocessor23

 

 

Commands section.

 

 

FIFO Data (0x24, 0x4C, 0x74, 0x9C, 0xC4, 0xEC) — Read Only

 

D15 – D0

FIFODATA31 – 16

FIFO Data - Two registers are provided for retrieving FIFO data. This

 

allows for 32-bit transfer. One sample of data per 16-bit register.

 

 

 

 

 

FIFO Data (0x26, 0x4E, 0x76, 0x9E, 0xC6, 0xEE) — Read Only

 

D15 – D0

FIFODATA15 – 0

FIFO Data - Two registers are provided for retrieving FIFO data. This

 

allows for 32-bit transfer. One sample of data per 16-bit register.

 

 

 

Results Register (0x28, 0x50, 0x78, 0xA0, 0xC8, 0xF0) — Read Only

 

 

Result Data - When a process data command is issued to the

D15 – D0

RESULT63 – 48

microprocessor, bits 63 through 48 of the 64-bit floating point result is

 

 

returned to this register. A status bit in the interrupt register is set.

Results Register (0x2A, 0x52, 0x7A, 0xA2, 0xCA, 0xF2) — Read Only

 

 

Result Data - When a process data command is issued to the

D15 – D0

RESULT47 – 32

microprocessor, bits 47 through 32 of the 64-bit floating point result is

 

 

returned to this register. A status bit in the interrupt register is set.

Results Register (0x2C, 0x54, 0x7C, 0xA4, 0xCB, 0xF4) — Read Only

D15 – D0

RESULT31 – 16

Result Data - When a process data command is issued to the

microprocessor, bits 31 through 16 of the 64-bit floating point result is

 

 

returned to this register. A status bit in the interrupt register is set.

Results Register (0x2E, 0x56, 0x7E, 0xA6, 0xCE, 0xF6) — Read Only

D15 – D0

RESULT15 – 0

Result Data - When a process data command is issued to the

microprocessor, bits 15 through 0 of the 64-bit floating point result is

 

 

returned to this register. A status bit in the interrupt register is set.

 

 

 

Reserved Registers (0xF8 – 0xFC)

 

D15 – D0

Unused

 

This is reserved for future use.

 

 

 

 

 

 

External Trigger Level - High-Speed Channels (0xFE) — Read & Write

 

 

 

 

High-Speed Input Trigger Source Slope – This bit sets the slope of the

 

 

HS_EXT_

 

input trigger for high-speed Channels 4 and 5.

 

D15

 

 

 

TRIG_SLOPE

 

0 = Positive

 

 

 

 

 

 

 

1 = Negative

 

 

 

 

Pon state = 0

 

D14 – D12

Unused

 

These bits are reserved for future use.

 

D11 – D 0

HS_EXT_TRIG 11 - 0

 

High-Speed External Trigger – Sets the level at which the high-speed

 

 

module triggers from an external source.
