or parallel). Only LEDUSER[1:0] are used in parallel mode. The content of the LEDUSER registers will be sent
out by the LED serial shift logic, or in parallel mode, a byte at a time.
Because in parallel mode there are only two user-defined registers, LEDUSER[7:2] is shared with LEDSIG[7:2].
For LEDSIG[j], where j = 2, 3, …, 6, the corresponding register is used for programming the LED pin
LED_BYTEOUT_[j]. The format is as follows:
For j = 2, 3, …, 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:

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)
