TABLE 13-24. DC Characteristics of Group 14 Input Pins
TABLE 13-25. DC Characteristics of Group 14 Output Pins
13.2.15 Group 15
Pin List:
IRQ1,3,4,5,6,7,8,9,10,11,12,14,15.
TABLE 13-26. DC Characteristics of Group 15 Output Pins
13.2.16 Group 16
Pin List:
DENSEL, DIR, DR1,0, HDSEL, MTR1,0, STEP, WDATA, WGATE.
TABLE 13-27. DC Characteristics of Group 16 Output Pins
a. Not tested. Guaranteed by design.
a. Output from PD7-0 is open-drain in all SPP modes, except in SPP Compatible mode when the setup
mode is ECP-based (FIFO) and bit 4 of the Control2 parallel port register is 1. (See Table 6-1 on page
112.) Otherwise, output from these signals is Level 2. External 4.7 K
Ω pull-up resistors should be used.
