Nomenclature
“Reserved” register bits, if written, should always be written “0”
R/W = register may be read and written via the utility bus
R-only or W-only = register is read-only or write-only
sticky = register bit is cleared after the register containing it is read; all sticky bits are read-only
“0” = ‘cleared’ or ‘not set’
“1” = ‘set’

1 - Good Signal
0 - Bad Signal
Reserved
Discard Receive Error Cells
On receipt of any cell with an error (e.g. short cell, invalid command mnemonic, receive HEC error (if enabled)), this
cell will be discarded and will not enter the receive FIFO.
If Bit 0 in this register is set (Interrupts Enabled), setting of this bit enables only "Received Cell Error" (as defined in bit
6) to trigger interrupt line."
Transmit Data Parity Check
Directs TC to check parity of TxDATA against parity bit located in TXPARITY.
Discard Received Idle Cells
Directs TC to discard received idle (VPI/VCI = 0 and GFC = 0) cells from PMD without signalling external systems.
Halt Tx
Halts transmission of data from TC to PMD and forces the TxD outputs to the "0" state."
UTOPIA Mode Select:
0 = cell mode, 1 = byte mode.
Enable Interrupt Pin (Interrupt Mask Bit)
Enables the INT output pin. If cleared, pin is always high and interrupt is masked. If set, an interrupt will be signaled
by setting the interrupt pin to "0". It doesn’t affect the Interrupt Status Registers."
