IL[2:0] — Interrupt Level
IARB3 — Interrupt Arbitration Bit 3
WOR — Wired-OR Mode
BSL — Bus Select
IN — Input Pin Status

MOTOROLA
The FLAG bit is set by hardware and cleared by software, or by system reset. Clear
the FLAG bit either by writing a zero to it, having first read the bit as a one, or by se-
lecting the DIS mode.
When the DASM generates an interrupt request, IL[2:0] determines which of the
interrupt request signals is asserted. When a request is acknowledged, the CTM4
compares IL[2:0] to a mask value supplied by the CPU32 to determine whether to
respond. IL[2:0] must have a value in the range of $0 (interrupts disabled) to $7
(highest priority).
This bit and the IARB[2:0] field in BIUMCR are concatenated to determine the interrupt
arbitration number for the submodule requesting interrupt service. Refer to D.7.1 BIU
Module Configuration Register for more information on IARB[2:0].
In the DIS, IPWM, IPM and IC modes, the WOR bit is not used. Reading this bit returns
the value that was previously written.
In the OCB, OCAB and OPWM modes, the WOR bit selects whether the output buffer
is configured for open-drain or normal operation.
This bit selects the time base bus connected to the DASM.
In the DIS, IPWM, IPM and IC modes, this read-only status bit reflects the logic level
on the input pin.
In the OCB, OCAB and OPWM modes, reading this bit returns the value latched on
the output flip-flop, after EDPOL polarity selection.
Writing to this bit has no effect.
0 = Output buffer operates in normal mode.
1 = Output buffer operates in open-drain mode.
0 = DASM is connected to time base bus A.
1 = DASM is connected to time base bus B.
