Serial I/O2
Serial I/O2
Serial I/O2 is used as the clock synchronous serial I/O and has an ordinary mode and an automatic transfer
mode. In the automatic transfer mode, serial transfer is performed through the serial I/O automatic transfer
RAM which has up to 256 bytes (addresses 0040016 to 004FF16).
The SRDY2, SBUSY2 and SSTB2 pins each have a handshake I/O signal function and can select either “H”
active or “L” active for active logic.
Specification
8-bit serial I/O mode (non-automatic transfer)
Automatic transfer serial I/O mode
Transfer data length: 8 bits
Full duplex mode / transmit-only mode selected by bit 5 at address 034216
When internal clock is selected (bit 2 at address 034216 = “0”) : selected by bits 5 to 7 at address 034816
When external clock is selected (bit 2 at address 034216 = “1”) : Input from SCLK21 pin, SCLK22 pin(Note 2)
When internal clock is selected : f(XIN)/4, f(XIN)/8, f(XIN)/16, f(XIN)/32, f(XIN)/64, f(XIN)/128, f(XIN)/256
When external clock is selected : input cycle 0.95
s or less
SSTB2 output / SBUSY2 input or output / SRDY2 input or output chosen
To start transmission / reception, the following requirements must be met:
_ Serial I/O initialization bit (bit 4 at address 034216) = “1”
_ When SBUSY2 input, or SRDY2 input is selected : selected input level = “H”
____________
_________
_ When SBUSY2 input, or SRDY2 input is selected : selected input level = “L”
Furthermore, if external clock is selected, the following requirements must
also be met:
_ Input level of SCLK21 or SCLK22 = “H”
To stop transmission and reception, set serial I/O initialization bit (bit 4 at
address 034216) to “0” regardless internal clock and external clock.
8-bit serial I/O mode : Interrupts requested when 8-bit data transfer is com-
pleted
Automatic transfer serial I/O mode :Interrupts requested when last receive
data transfer to Automatic transfer RAM
SOUT2 P-channel output disable function
CMOS output or N-channel open-drain output can be selected
LSB first/MSB first selection
Whether transmission/reception begins with bit 0 or bit 7 can be selected
Serial I/O2 clock pin select bit
Serial clock input/output can be selected; SCLK21 or SCLK22
SBUSY output, SSTB2 output select function (only automatic transfer serial
mode)
SBUSY output, SSTB2 output can be selected; 1-byte data transfer unit or all
data transfer unit
SOUT2 pin control bit
Either output active or high-impedance can be selected as a SOUT2 pin state at
serial non-transfer .
Note 1: It is necessary to set the serial I/O clock pin select bit ( bit 7 at address 034216)
