Figure 14 - 72 Example of Contents of Registers for UART Transmission of UART (UARTq) (2/2)
(e) Serial output register m (SOm)... Sets only the bits of the target channel.
(f) Serial output enable register m (SOEm)... Sets only the bits of the target channel to 1.
(g) Serial channel start register m (SSm)... Sets only the bits of the target channel to 1.
Note Before transmission is started, be sure to set to 1 when the SOLmn bit of the target channel is set to 0, and
set to 0 when the SOLmn bit of the target channel is set to 1. The value varies depending on the
communication data during communication operation.
Remark 1. m: Unit number (m = 0, 1), n: Channel number (n = 2), mn = 02, 12, q: UART number (q = 1, 3)
Remark 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
