ADSP-21368 SHARC Processor Hardware Reference A-115
Register Reference
DPI Resistor Pull-up Enable Register
(DPI_PIN_PULLUP)
This 16-bit read/write register is shown in Figure A-45. Bits 13–0 of this
register control the enabling/disabling 22.5 KΩ pull-up resistor on
DPI_P0[13:0]. Setting a bit to 1 enables a pull-up resistor on the corre-
sponding pin. After RESET, the value of this register is 0xFFFFF, which
means pull-ups are enabled on all 14 DPI pins.
DAI_IRPTL_RE Rising Edge Interrupt Mask Register 0x2481
DAI_IRPTL_FE Falling Edge Interrupt Mask Register 0x2480
