12.4.2 Stopping the operation by channels
The stopping of the operation by channels is set using each of the following registers.
Figure 12-21. Each Register Setting When Stopping Operation by Channels
(a) Serial channel stop register 0 (ST0) … This register is a trigger register that is used to enable stopping
communication/count by each channel.
(b) Serial Channel Enable Status Register 0 (SE0) … This register indicates whether data
transmission/reception operation of each channel is enabled or stopped.
(c) Serial output enable register 0 (SOE0) … This register is a register that is used to enable or stop output
of the serial communication operation of each channel.
(d) Serial clock output register 0 (CKO0) …This register is a buffer register for serial output of each
channel.

1: Serial clock output value is “1”
* When using pins corresponding to each channel as port function pins, set the corresponding CKO0n bit to “1”.
(e) Serial output register 0 (SO0) …This register is a register that is used to set a value of serial output of
each channel.
Note 16-pin products only.
Remarks 1. n: Channel number (n = 0, 1)
2. : Setting disabled (fixed by hardware), 0/1: Set to 0 or 1 depending on the usage of the user

0: Operation stops
* The SE0 register is a read-only status register. Operation is stopped by using the ST0
register.
For a channel whose operation is disabled, the value of the CKO0n bit of the SO0 register
can be set by software.
