79 | nSA_SKT0_IOI | I | IO Select 16. (input) Acknowledge | Pull high with |
| S16 |
| from the PCMCIA card that the | 10Kohm |
|
|
| current address is a valid 16 bit |
|
|
|
| wide I/O address. |
|
80 | SA_SKT0_VCC | P | PCMCIA/CF slot 0 power pin. | Powered |
81 | nSA_SKT1_IOI | I | PCMCIA/CF slot 0 IO Select 16. | Pull high with |
| S16 |
| Acknowledge from the PCMCIA | 10Kohm |
|
|
| card that the current address is a |
|
|
|
| valid 16 bit wide I/O address. |
|
82 | nSA_PWR_ON | I | System suspend/wakeup input pin. | Pull high with |
|
|
| Falling edge triggered. | 10Kohm |
83 | nBATT_FALT | I | Main Battery Fault. Signals that | Pull high with |
|
|
| main battery is low or removed. | 100Kohm |
|
|
| Assertion causes PXA255 |
|
|
|
| processor to enter sleep mode or |
|
|
|
| force an Imprecise Data Exception, |
|
|
|
| which cannot be masked. PXA255 |
|
|
|
| processor will not recognize a |
|
|
|
| wakeup event while this signal is |
|
|
|
| asserted. Minimum assertion time |
|
|
|
| for nBATT_FAULT is 1 ms. |
|
84 | nSW_RESET | I | System software reset input pin. | Pull high with |
|
|
| Falling edge triggered. | 10Kohm |
85 | nVDD_FALT | I | VDD Fault. Signals that the main | Pull high with |
|
|
| power source is going out of | 100Kohm |
|
|
| regulation. nVDD_FAULT causes |
|
|
|
| the PXA255 processor to enter |
|
|
|
| sleep mode or force an Imprecise |
|
|
|
| Data Exception, which cannot be |
|
|
|
| masked. nVDD_FAULT is ignored |
|
|
|
| after a wakeup event until the |
|
|
|
| power supply timer completes |
|
|
|
| (approximately 10 ms). Minimum |
|
|
|
| assertion time for nVDD_FAULT is |
|
|
|
| 1 ms. |
|
86 | nRESET_OUT | O | Reset Out. Asserted when | No pulling |
|
|
| nRESET is asserted and deasserts |
|
|
|
| after nRESET is deasserted but |
|
|
|
| before the first instruction fetch. |
|
|
|
| nRESET_OUT is also asserted for |
|
|
|
| “soft” reset events: sleep, |
|
|
|
| watchdog reset, or GPIO reset. |
|
87 | GND | P | Ground | - |
88 | PWR_EN |
| Power Enable for the power | Pull high with |
|
| O | supply. (output) When negated, it | 100Kohm |
|
|
| signals the power supply to |
|
|
|
| remove power to the core because |
|
|
|
| the system is entering sleep mode. |
