BIT SYMBOL DESCRIPTION

BIT SYMBOL DESCRIPTION
7 AIOF Auto-increment off. 0 = auto-increment enabled; 1 = auto-increment disabled.
6GATEGate. 0=I
2
C-bus outputs (SDAG and SCLG) are controllable by the shortgate or the
autogate function; 1 = I
2
C-bus outputs are enabled.
5 SGAT Shortgate. 1=I
2
C-bus outputs (SDAG and SCLG) are enabled for a single
transmission following this control and disabled automatically.
4 to 0 SA[4:0] Data byte select. The subaddress value is auto-incremented when AIOF = 0 and will
revert from SA = 30 to SA = 0. SA = 31 can only be accessed via direct subaddress
selection, in which case auto-increment will revert from SA = 31 to SA = 0; see
Table 13.
