MT9075A
Preliminary Information
4-142
of memory is selected, it is only necessary to write to
the CAR when a different page is to be accessed.
See Figures 11 and 12 for timing requirements.
Please note that for microprocessors with read/write
cycles less than 200 ns, a wait state or a dummy
operation (for C programming) between two
successive read/write operations to the HDLC FIFO
is required.
Table 5 associates the MT9075A control and status
pages with access and page descriptions.
ST-BUS Streams
The ST-BUS stream can also be used to access
channel associated signalling nibbles. CSTo contains
the received channel associated signalling bits (e.g.,
ITU-T R1 and R2 signalling), and when control bit
RPSIG (page 01H, address 1AH) is set to 0, CSTi is
used to control the transmit channel associated
signalling. The DSTi and DSTo streams contain the
transmit and receive voice and digital data.
Identification Code
The MT9075A shall be identified by the code
10101010, read from the identification code status
register (page 03H, address 1FH).
Reset Operation (Initialization)
The MT9075A can be reset using the hardware
RESET pin (pin 11 in PLCC, pin 84 in MQFP, see pin
description for external reset circuit requirements) or
the software reset bit RST (page 01H, address 11H).
When the device emerges from its reset state it will
begin to function with the default settings described
in Table 6. A reset operation takes 1 full frame (125
us) to complete.
