(5) Higher 7 bits of the serial data register mn (SDRmn)
SDRmn
Symbol
Cautions 1. Be sure to clear bit 8 to “0”.
For the function of the lower 8 bits of SDRmn, see 11.2 Configuration of Serial Array Unit.
SDRmn can be read or written in 16-bit units.
However, the higher 7 bits can be written or read only when the operation is stopped (SEmn = 0). During
operation (SEmn = 1), a value is written only to the lower 8 bits of SDRmn. When SDRmn is read during
operation, 0 is always read.
Reset signal generation clears this register to 0000H.
Remarks 1. For the function of the lower 8 bits of SDRmn, see 11.2 Configuration of Serial Array Unit.
SDRmn is the transmit/receive data register (16 bits) of channel n. Bits 7 to 0 function as a transmit/receive
buffer register, and bits 15 to 9 are used as a register that sets the division ratio of the operation clock (MCK).
If the CCSmn bit of serial mode register mn (SMRmn) is cleared to 0, the clock set by dividing the operating
clock by the higher 7 bits of SDRmn is used as the transfer clock.

2. Setting SDRmn[15:9] = (0000000B, 0000001B) is prohibited when UART is used.
3. Setting SDR02[15:9] = 0000000B is prohibited when simplified I
4. Do not write eight bits to the lower eight bits if operation is stopped (SEmn = 0). (If these
