 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Namco C219 is a 16-channel PCM sound chip that's a lot like C140, but has a noise generator, surround effect and a different µ-law curve. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | this chip features: | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | - stereo soft panning | 
					
						
							|  |  |  | - accepts either 8-bit PCM or proprietary 8-bit µ-law compressed PCM samples |

 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | this chip is rather unique when it comes to sample memory. be sure to read this notice. |

										 |  |  | the channels are in groups of four. a sample bank (128KB) may be selected for each group. | 
					
						
							|  |  |  | if a sample that is on a different bank plays in a group, the group is switched to that bank, and other channels will be silenced. |

							|  |  |  | - `12xy`: **set invert mode.** | 
					
						
							|  |  |  |   - if `x` is 1 or higher, surround is enabled. | 
					
						
							|  |  |  |   - if `y` is 1 or higher, invert is enabled. |
