Function Documentation

nile_bank_clear_mask()

void nile_bank_clear_mask

(

void

)

Adjust banking registers and clear NILE_SEG_MASK.

Note that if executing from ROML, this is only guaranteed safe for >=1MB cartridge images, due to the linear address.

nile_bank_lock()

void nile_bank_lock

(

void

)

Re-lock RAM/ROM0/ROM1 banks.

nile_bank_unlock()

void nile_bank_unlock

(

void

)

Adjust banking registers and unlock RAM/ROM0/ROM1 banks.

This variant is safe for <1MB cartridge images.

nile_io_unlock()

void nile_io_unlock ( void )

inlinestatic

Unlock I/O ports used to control the cartridge FPGA.

Definition at line 56 of file fpga.h.

nile_irq_ack()

void nile_irq_ack ( uint8_t mask )

inlinestatic

Acknowledge the specified FPGA interrupts.

Definition at line 84 of file fpga.h.

nile_irq_disable()

void nile_irq_disable ( uint8_t mask )

inlinestatic

Disable the specified FPGA interrupts.

Definition at line 70 of file fpga.h.

nile_irq_disable_all()

void nile_irq_disable_all ( void )

inlinestatic

Disable all FPGA interrupts.

Definition at line 77 of file fpga.h.

nile_irq_enable()

void nile_irq_enable ( uint8_t mask )

inlinestatic

Enable the specified FPGA interrupts.

Definition at line 63 of file fpga.h.

nile_irq_set_enabled()

void nile_irq_set_enabled ( uint8_t mask )

inlinestatic

Set the specified FPGA interrupts as enabled; disable all other interrupts.

Definition at line 92 of file fpga.h.

nile_soft_reset()

void nile_soft_reset

(

void

)

Jump back to cartridge IPL0 (soft reset).

Make sure to run nilefs_eject() first if you were using the TF card.
