uDigital Input Mode Setting:

I_ACK: Input ACK Enable

1:Input ACK is enabled (input ACK will be asserted after input data is read by CPU or written to input FIFO)

0:Input ACK is disabled

I_REQ: Input REQ Strobe Enabled

1:Use I_REQ edge to latch input data

0:I_REQ is disabled

I_TIME0: Input Timer 0 Enable

1:Input is sampled by falling edge of Counter 0 output (COUT0)

0:Input Timer 0 is disabled

I_FIFO: Input FIFO Enable Mode

1:Input FIFO is enabled (input data is saved to input FIFO)

0:Input FIFO is disabled

TRGPOL: Input Trigger Polarity

1:I_TRG is Rising Edge Active

0:I_TRG is Falling Edge Active

I_TRG: External Trigger Enable

1:Wait until I_TRG signal is active, digital input sampling will begin after a rising or falling edge of I_TRG is coming.

0:Start input sampling immediately (if input control register is set)

DIN_EN: Digital Input Enable

1: Digital Input Enable

0:Digital Input Disabled, when this bit is set as 0, all digital input operation will be stopped.

uDigital Output Mode Setting:

O_ACK: Output ACK Enable

1:Output ACK is enabled, the output circuit will wait for O_ACK after O_REQ strobe is asserted.

0:Output ACK is disabled

O_REQ: Output REQ Enable

1:Output REQ is enabled, an O_REQ strobe will be generated after output data is ready

0:Output REQ is disabled

O_TIME1: Output Timer 1 Enable

1:Output Timer 1 is enabled, output data is moved from output FIFO to DO registers when output of Counter1 goes low.

0:Output Counter 1 is disabled

O_FIFO: Output FIFO Enable

1:Output FIFO is enabled (output data is moved from output FIFO)

0:Output FIFO is disabled
