Note: The IXP28XX CSR Transmit Enable Register (SP_TXE) can be used to delay the data and relevant
Mode 3 32-Bit Write Transfer
To pack the 32-bit write data, the IXP28XX network processor drives a byte of write data onto the
SP_AD bus in four cycles that are qualified with the rising edge of the SP_CP signal, with the
SP_OE_L && SP_DIR signal being active, i.e., SP_OE_L = 0 and SP_DIR = 1. On every rising
edge of the SP_CP signal with SP_OE_L && SP_DIR asserted, the data is shifted into a register
implemented in the glue logic device – from least significant byte (LSB) through most significant
byte (MSB).
Slowport signals in relation to the SP_CLK. For programming information, refer to the Intel®
IXP2800 Network Processor Hardware Reference Manual.
