Mode Select
In Hardware Mode, operation is determined by the Mode Select pins. The states of these pins are continu-
ally scanned for any changes; however, the mode should only be changed while the device is in reset
(RST pin low) to ensure proper switching from one mode to another. These pins require connection to sup-
ply or ground as outlined in Figure 7. For M0, M1, and M2, supply is VLC. For M3 and M4, supply is VLS.
Tables 4 - 6 show the decode of these pins.
In Software Mode, the operational mode and data format are set in the FM and DIF registers. See “PCM
