(4) Clocked serial interface transmit buffer register n (SOTBn)
(5) Selector
(6) Serial clock controller
(7) Serial clock counter
(8) Interrupt controller
Remarks 1. m = 2 when n = 0
The SOTBn register is an 8-bit buffer register for storing transmit data.
The selector selects the serial clock to be used.
The serial clock controller controls the supply of serial clocks to the shift register. When an internal clock is
used, it also controls the clocks that are output to the SCKn pin.
The serial clock counter counts serial clocks that are output or input during transmit and receive operations
and checks that 8-bit data has been transmitted or received.
The interrupt controller controls whether or not an interrupt request is generated when the serial clock counter
has counted eight serial clocks.
