Function:
The bits of this register serve as a mask for the Status sources found in the register “Status - Address 0Dh”
on page 42. If a mask bit is set to 1, the error is unmasked, meaning that its occurrence will affect the status
register. If a mask bit is set to 0, the error is masked, meaning that its occurrence will not affect the status
register. The bit positions align with the corresponding bits in the Status register.

Function:
The two Status Mode registers form a 2-bit code for each Status register function. There are three ways to
update the Status register in accordance with the status condition. In the Rising-Edge Active Mode, the sta-
tus bit becomes active on the arrival of the condition. In the Falling-Edge Active Mode, the status bit be-
comes active on the removal of the condition. In Level-Active Mode, the status bit is active during the
condition.

6.17.1 E to F C-Data Buffer Transfer Inhibit (Bit 6)
Function:
When cleared, C-data E to F buffer transfers are allowed. When set, C-data E to F buffer transfers are
inhibited. See “IEC60958-3 Channel Status (C) Bit Management” on page 52.
6.17.2 C-Data Access Mode (Bit 5)
Function:
When cleared, the C-data buffer will operate in One-byte control port access mode. When set, the C-data
buffer will operate in Two-byte control port access mode. See “IEC60958-3 Channel Status (C) Bit Man-
agement” on page 52.
