17.2 Configuration of Serial Interfaces SIO30 and SIO31
(1) Serial I/O shift register 3n (SIO3n)
328
Serial interface SIO3n consists of the following hardware.
This is an 8-bit register that performs parallel-serial conversion and serial transmit/receive (shift operations)
synchronized with the serial clock.
SIO3n is set by an 8-bit memory manipulation instruction.
When 1 is set to bit 7 (CSIE3n) of serial operation mode register 3n (CSIM3n), a serial operation can be started
by writing data to or reading data from SIO3n.
When transmitting, data written to SIO3n is output to the serial output (SO3n).
When receiving, data is read from the serial input (SI3n) and written to SIO3n.
RESET input makes SIO3n undefined.
Caution
Remark n = 0, 1:
n = 0:
Register
Control registers
Do not access SIO3n during a transfer operation unless the access is triggered by a transfer
start (read operation is disabled when MODEn = 0 and write operation is disabled when MODEn
= 1).
