Status Page 4
Tables 59 to 66 describe the bit functions of the page 4
status registers and counters. The Internal Vector
Status Word is cleared automatically after it is read by
the microprocessor. The RESET and RST functions
do not affect the page 4 counters. Therefore,
individual counters must be initialized to a starting
value by a write operation or a counter load operation
(Table 43) in ST-BUS control mode. When presetting
or clearing the BPV counter, BPV7-BPV0 should be
written to first, and BPV15-BPV8 should be written to
last.

Interrupt Vector Bits 7 to 0. The inter-
rupt vector status word contains an
interrupt vector that indicates the cat-
egory of the last interrupt. See the
section on interrupts.
