91 / 174 page  6.0 System Wake-Up Control (SWC) (Continued) 91 www.national.com Revision 1.1 6.3.4 Advanced LED Control Register (ALEDCTL) This register configures the advanced LED control of the two LEDs connected to pins GRN_LED and YLW_LED of the PC87373 device. It is reset to 00h. Power Well: VSB3 Location: Offset 02h, when LED_OPT = 00 in the SWC_CTL register Type: R/W or RO Bit 76 5 43210 Name Reserved LEDCFG LEDPOL Reserved LEDMOD Reset 0 0 0 00000 Bit Description 7-6 Reserved. 5 LEDCFG (LED Configuration). This bit enables the use of either two regular LEDs, connected to the GRN_LED and YLW_LED pins or one dual-colored LED, connected between the two pins (see Figure 16 on page 85). 0: One dual-colored LED (default) 1: Two regular LEDs 4 LEDPOL (LED Polarity). This bit determines the polarity of GRN_LED and YLW_LED outputs. An active output, according to this bit setting, turns the LED on. For the dual-colored LED configuration, changing the polarity reverses the LED colors. The configurations described here apply to the “two regular LEDs” option only; see Table 32 on page 86). 0: Active high: for connection configuration “b” in Figure 16 on page 85 (default) 1: Active low: for connection configuration “a” in Figure 16 on page 85 3-2 Reserved. 1-0 LEDMOD (LED Operation Mode). These bits control the operation mode of GRN_LED and YLW_LED in each power state. Table 35 shows the behavior of the two LED outputs as a function of the system power state. Table 35.
