Bit #
Name
Bit 7: INT303. This bit indicates the status of the INT303 line.
Bit 6: ENRLOS1. This bit enables the RLOS1 LED. This should not be enabled when driving TECLK from the
DS26303.
Bit 5: CLKE. This bit sets the CLKE pin on the DS26303. This is only active when SPI (Bit 0) is HIGH. If SPI (Bit 0)
is low, CLKE is always low.
Bit 4: SPI_SWAP. This bit sets the BSWP/A5 pin on the DS26303. This is only active when SPI (Bit 0) is HIGH.
Bit 3: SPI. This bit sets up the FPGA to use serial mode. This bit also changes the mode pin on the DS26303.
Bit 2: OE. This bit controls the OE pin to the DS26303.
Bits 1 and 0: MCLK1 and MCLK0. These bits control the MCLK pin to the DS26303.
BID is read-only with a value of 0xD.
XBIDH is read-only with a value of 0x0.
XBIDM is read-only with a value of 0x1.
XBIDL is read-only with a value of 0x6.
BREV is read-only and displays the current fab revision.
AREV is read-only and displays the current assembly revision.
PREV is read-only and displays the current PLD firmware revision.
If INT303 = LOW, there is no hardware interrupt on the DS26303.
If INT303 = HIGH, there is a hardware interrupt on the DS26303.
If ENRLOS1 = LOW, the RLOS1 LED is not enabled.
If ENRLOS1 = HIGH, the RLOS1 LED is enabled and lights when RLOS1 is high.
If CLKE = LOW, SDO is clocked out on the rising edge of SCLK.
If CLKE = HIGH, SDO is clocked out on the falling edge of SCLK.
If SPI_SWAP = LOW, the SPI bus is LSB first.
If SPI_SWAP = HIGH, the SPI bus is MSB first.
If SPI = LOW, the parallel bus is used for all read/write access. This also sets the MODE pin on the
If SPI = HIGH, the SPI bus is used for all read/write access. This also sets the MODE pin on the DS26303
