Module libnoentiendo::memory::mos652x

The various interface adapters (6520, 6522, 6526) for the MOS 6502 CPU.

Structs

• Cia
  The MOS 6526 Complex Interface Adapter (CIA). Contains two ports, two timers, a real-time clock, a shift register, and interrupt registers.
• InterruptRegister
  Registers for interrupt flags and interrupt enable bits. Each bit from 0 to 6 corresponds to an interrupt source.
• Pia
  The MOS 6520 Peripheral Interface Adapter (PIA), containing two ports and some control lines.
• PortRegisters
  A port and its associated registers on the MOS 6522 VIA or MOS 6526 CIA.
• ShiftRegister
  The shift register used by the MOS 6522 VIA and MOS 6526 CIA.
• Timer
  A timer circuit on the MOS 6522 VIA or MOS 6526 CIA.
• Via
  The MOS 6522 Versatile Interface Adapter (VIA). Contains two ports, two timers, a shift register, and some interrupt and control registers. Source: http://archive.6502.org/datasheets/mos_6522_preliminary_nov_1977.pdf

Enums

• TimerClockSource
  The source of the timer’s clock, which controls the rate at which its clock decrements.
• TimerOutput
  The manner in which the timer will output signals to the port, if at all.
