The serial array unit consists of the following registers.
<Registers of unit> m: Unit number (m = 0, 1)
(1) Peripheral enable register 0 (PER0)
(2) Serial clock select register m (SPSm)
(3) Serial channel enable status register m (SEm)
(4) Serial channel start register m (SSm)
(5) Serial channel stop register m (STm)
(6) Serial output enable register m (SOEm)
(7) Serial output register m (SOm)
(8) Noise filter enable register 0 (NFEN0)
Bit 2 of this register enables or stops the operation of serial array unit 0, and bit 3 enables or stops the
operation of serial array unit 1. By default, both the units are stopped from operating.
This register is used to set the division ratio of CK0 clock and CK1 clock that are generated by dividing the
peripheral hardware clock. The CK0 and CK1 clocks are supplied to all channels 0 to 3 of the unit.
This register indicates whether data transmission/reception operation of each channel is enabled or stopped.
This is a trigger register that is used to clear the shift register and start transmission/reception of data by each
channel.
This is a trigger register that is used to stop the shift register and stop data transmission/reception by each
channel.
This register is used to enable or stop output of serial data by each channel.
This is a buffer register of serial clock output and serial data output. The value of this register is output from the
serial clock output pin and serial data output pin of each channel.
This register is used to set whether the noise filter can be used for the serial data input signal to each channel.
