SMRmn
(3) Serial mode register mn (SMRmn)
Symbol
SMRmn is a register that sets an operation mode of channel n. It is also used to select an operation clock
(MCK), specify whether the serial clock (SCK) may be input or not, set a start trigger, an operation mode (CSI,
UART, or I
the UART mode.
Rewriting SMRmn is prohibited when the register is in operation (when SEmn = 1). However, the MDmn0 bit
can be rewritten during operation.
SMRmn can be set by a 16-bit memory manipulation instruction.
Reset signal generation sets this register to 0020H.
Caution Be sure to clear bits 13 to 9, 7, 4, and 3 to “0”. Be sure to set bit 5 to “1”.
Remark
F0154H, F0155H (SMR12), F0156H, F0157H (SMR13)
Operation clock MCK is used by the edge detector. In addition, depending on the setting of the CCSmn bit and the
higher 7 bits of the SDRmn register, a transfer clock (TCLK) is generated.
Transfer clock TCLK is used for the shift register, communication controller, output controller, interrupt controller,
and error controller. When CCSmn = 0, the division ratio of MCK is set by the higher 7 bits of the SDRmn register.
Transfer is started when the above source is satisfied after 1 is set to the SSm register.
