4. SRDY1 output signal
The SRDY1 output is a transmit/receive enable signal which informs
the serial transfer destination that transmit/receive is ready. In the
initial status, when the serial I/O initialization bit (b4) is reset to “0,”
________
the SRDY1 output goes to “L” and the SRDY1 output goes to “H”. After
transmitted data is stored in the serial I/O1 register (address 001B16)
and a transmit/receive operation becomes ready, the SRDY1 output
________
goes to “H” and the SRDY1 output goes to “L”. When a transmit/
receive operation is started and the transfer clock goes to “L”, the
________
SRDY1 output goes to “L” and the SRDY1 output goes to “H”.
5. SRDY1 input signal
The SRDY1 input signal becomes valid only when the SRDY1 input
and the SBUSY1 output are used. The SRDY1 input is a signal for
receiving a transmit/receive ready completion signal from the serial
transfer destination.
When the internal synchronous clock is selected, input a low level
_________
signal into the SRDY1 input and a high level signal into the SRDY1
input in the initial status in which the transfer is stopped.
When an “H” level signal is input into the SRDY1 input and an “L”
_________
level signal is input into the SRDY1 input for a period of 1.5 cycles or
more of transfer clock, transfer clocks are output from the SCLK1
output and a transmit/receive operation is started.
After the transmit/receive operation is started and an “L” level sig-
nal is input into the SRDY1 input and an “H” level signal into the
_________
SRDY1 input, this operation cannot be immediately stopped.
After the specified number of bits are transmitted and received, the
transfer clocks from the SCLK1 output is stopped. The handshake
unit of the 8-bit serial I/O and that of the automatic transfer serial
I/O are of 8 bits.
When the external synchronous clock is selected, the SRDY1 input
becomes one of the triggers to output the SBUSY1 signal.
_________
To start a transmit/receive operation (SBUSY1 output: “L,” SBUSY1
output: “H”), input an “H” level signal into the SRDY1 input and an “L”
_________
level signal into the SRDY1 input, and also write transmit data into
the serial I/O1 register.
