Tests bits 2 and 6 of the object attribute at ObjectAttributeValue. When both allow it, the display flag chooses the mode.
|
||||
| CheckDisplayBitsTwoAndSix | C4B2 | XOR A | Point HL at the object attribute and go to CheckDisplayBitsTwoAndSix_0 if bit 2 is clear. | |
| C4B3 | LD HL,$A01D | |||
| C4B6 | BIT 2,(HL) | |||
| C4B8 | JR Z,CheckDisplayBitsTwoAndSix_0 | |||
| C4BA | LD A,$04 | Go to CheckDisplayBitsTwoAndSix_0 if bit 6 of the object attribute is set. | ||
| C4BC | BIT 6,(HL) | |||
| C4BE | JR NZ,CheckDisplayBitsTwoAndSix_0 | |||
| C4C0 | LD A,($A01E) | Read the display. | ||
|
Bits 0 and 1 of the display flag choose the mode.
|
||||
| C4C3 | AND $03 | Jump to CheckDisplayBitsTwoAndSix_0 with 05 if bits 0 and 1 of the display flag are both set. | ||
| C4C5 | CP $03 | |||
| C4C7 | LD A,$05 | |||
| C4C9 | JR Z,CheckDisplayBitsTwoAndSix_0 | |||
| C4CB | LD A,$07 | Use 07 for the display. | ||
| CheckDisplayBitsTwoAndSix_0 | C4CD | LD ($A010),A | Store it in the display mode. | |
| C4D0 | RET | Return. | ||
