Register Description

The HSS Transmit Address register is used as the base pointer address for the next HSS block transmit transfer.

HSS Transmit Counter Register [0xC07E] [R/W]

Register Description

The HSS Transmit Counter register designates the block byte length for the next HSS transmit transfer. Load this register with the word count minus one to start the block transmit transfer. As each byte is transmitted this register value is decremented. When read, this register indicates the remaining length of the transfer.

Counter (Bits [9:0])

The Counter field value is equal to the word count minus one giving a maximum value of 0x03FF (1023) or 2048 bytes. When the transfer is complete this register returns 0x03FF until reloaded.

Reserved

Write all reserved bits with ’0’.
