Bits [7:4]
Signal select: 0: do not select
1: select the corresponding bit
For j = 2, 3, 4, 5, the value of LED_BYTEOUT_[j] equals the logical AND of all selected bits. For j = 6, the value
is equal to the logical OR. Therefore, the programmable LEDSIG[5:2] registers allow any conjunctive formula
including any of the 4 status bits (COL, FDX, SP1, SP0) or their negations to be sent to the
LED_BYTEOUT_[5:2] pins. Similarly, the programmable LEDSIG[6] register allows any disjunctive formula
including any of the 4 status bits or their negations to be sent to pin LED_BYTEOUT_[6].
LEDSIG[7] is used for programming both LED_BYTEOUT_[1] and LED_BYTEOUT_[0]. As we will see, it has
other functions as well. The format is as follows:

Bits [7]
Global output polarity: this bit controls the output polarity of all LED_BYTEOUT_ and
LED_PORT_SEL pins.
(Default 0)
0: do not invert polarity (LED_BYTEOUT_[7:0] are high activated; LED_PORT_SEL[9:0] are low
activated)
1: invert polarity (LED_BYTEOUT_[7:0] are low activated; LED_PORT_SEL[9:0] are high activated)
Bits [6:4]
Signal select:
0: do not select
1: select the corresponding bit
The value of LED_BYTEOUT_[1] equals the logical OR of all selected bits.
(Default 110)

0: do not invert
1: invert
Bits [2:0]
Signal select:
0: do not select
1: select the corresponding bit
The value of LED_BYTEOUT_[0] equals the logical OR of all selected bits. (
