DS2152
58 of 97
Like the other status registers in the DS2152, the user will always precede a read of any of the four
registers with a write. The byte written to the register will inform the DS2152 which of the latched bits
the user wishes to read and have cleared (the real-time bits are not affected by writing to the status
register). The user will write a byte to one of these registers, with a 1 in the bit positions he or she wishes
to read and a 0 in the bit positions he or she does not wish to obtain the latest information on. When a 1 is
written to a bit location, the read register will be updated with current value and it will be cleared. When a
0 is written to a bit position, the read register will not be updated and the previous value will be held. A
write to the status and information registers will be immediately followed by a read of the same register.
The read result should be logically ANDed with the mask byte that was just written and this value should
be written back into the same register to insure that bit does indeed clear. This second write step is
necessary because the alarms and events in the status registers occur asynchronously in respect to their
access via the parallel port. This write-read-write (for polled driven access) or write-read (for interrupt-
driven access) scheme allows an external microcontroller or microprocessor to individually poll certain
bits without disturbing the other bits in the register. This operation is key in controlling the DS2152 with
higher-order software languages.
Like the SR1 and SR2 status registers, the FDLS register has the unique ability to initiate a hardware
interrupt via the
INT output pin. Each of the events in the FDLS can be either masked or unmasked from
the interrupt pin via the FDL Interrupt Mask Register (FIMR). Interrupts will force the
INT pin low when
the event occurs. The
INT pin will be allowed to return high (if no other interrupts are present) when the
user reads the event bit that caused the interrupt to occur.
12.1.2 Basic Operation Details
To allow the DS2152 to properly source/receive data from/to the HDLC and BOC controller the legacy
FDL circuitry (which is described in Section 12.2) should be disabled and the following bits should be
programmed as shown:
TCR1.2 = 1 (source FDL data from the HDLC and BOC controller)
TBOC.6 = 1 (enable HDLC and BOC controller)
CCR2.5 = 0 (disable SLC-96 and D4 Fs-bit insertion)
CCR2.4 = 0 (disable legacy FDL 0 stuffer)
CCR2.1 = 0 (disable SLC-96 reception)
CCR2.0 = 0 (disable legacy FDL 0 stuffer)
IMR2.4 = 0 (disable legacy receive FDL buffer full interrupt)
IMR2.3 = 0 (disable legacy transmit FDL buffer empty interrupt)
IMR2.2 = 0 (disable legacy FDL match interrupt)
IMR2.1 = 0 (disable legacy FDL abort interrupt)
As a basic guideline for interpreting and sending both HDLC messages and BOC messages, the following
sequences can be applied:
