- Parameters:
-
| address | value to read from |
- Returns:
- value at address

uint8_t |
value | |
|
) |
| | [inline, virtual] |
Bank write.
Override this method if you expect write operations on your bank. Leave unimplemented if it's logically/operationally impossible for writes to ever arrive to bank.

| value | value to write |
Implements Bank.
void c64cia1::reset |
