4.2 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
Control (Address 03h)” on page 34.
