TSOCI

The TSOCI bit is set high when the TSOC input is sampled high during any position other

than the first word of the selected data structure. The write address counter is reset to the first

word of the data structure when TSOC is sampled high. This bit is reset immediately after a

read to this register.

FOVRI

The FOVRI bit is set high when an attempt is made to write into the FIFO when it is already

full. This bit is reset immediately after a read to this register

TPRTYI

The TPRTYI bit indicates if a parity error was detected on the TDAT input bus. When logic

one, the TPRTYI bit indicates a parity error over the active TDAT bus. The active TDAT bus

is TDAT[15:0] when ATM8 is tied low and is TDAT[7:0] when ATM8 is tied high. This bit is

cleared when this register is read. Odd or even parity is selected using the TPTYPE bit.

TSOCE

The TSOCE bit enables the generation of an interrupt when the TSOC input is sampled high

during any position other than the first word of the selected data structure. When TSOCE is

set to logic one, the interrupt is enabled.

FOVRE

The FOVRE bit enables the generation of an interrupt due to an attempt to write the FIFO

when it is already full. When FOVRE is set to logic one, the interrupt is enabled.
