Figure 12-69. Example of Contents of Registers for UART Transmission (UART0) (2/2)
(e) Serial clock output register 0 (CKO0) … Sets only the bits of the target channel.
(f) Serial output register 0 (SO0) … Sets only the bits of the target channel.
(g) Serial output enable register 0 (SOE0) … Sets only the bits of the target channel to 1.
(h) Serial channel start register 0 (SS0) … Sets only the bits of the target channel to 1.
Note Before transmission is started, be sure to set to 1 when the SOL00 bit of the target channel is set to 0, and
set to 0 when the SOL00 bit of the target channel is set to 1. The value varies depending on the
communication data during communication operation.
Remarks 1. n = 0
2. : Setting disabled (set to the initial value)
×: Bit that cannot be used in this mode (set to the initial value when not used in any mode)
0/1: Set to 0 or 1 depending on the usage of the user
