(1) Peripheral enable register 0 (PER0)
(2) Serial clock select register m (SPSm)
Symbol
PER0
PER0 is used to enable or disable use of each peripheral hardware macro. Clock supply to a hardware macro
that is not used is stopped in order to reduce the power consumption and noise.
When serial array unit 0 is used, be sure to set bit 2 (SAU0EN) of this register to 1.
When serial array unit 1 is used, be sure to set bit 3 (SAU1EN) of this register to 1.
PER0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. When setting serial array unit m, be sure to set SAUmEN to 1 first. If SAUmEN = 0, writing
Remark m: Unit number (m = 0, 1)
SPSm is a 16-bit register that is used to select two types of operation clocks (CKm0, CKm1) that are
commonly supplied to each channel. CKm1 is selected by bits 7 to 4 of SPSm, and CKm0 is selected by bits 3
to 0.
Rewriting SPSm is prohibited when the register is in operation (when SEmn = 1).
SPSm can be set by a 16-bit memory manipulation instruction.
The lower 8 bits of SPSm can be set with an 8-bit memory manipulation instruction with SPSmL.
Reset signal generation clears this register to 0000H.

2. After setting the PER0 register to 1, be sure to set the SPSm register after 4 or more
3. Be sure to clear bit 1 of PER0 register to 0.

to a control register of serial array unit m is ignored, and, even if the register is read, only
the default value is read (except for input switch control register (ISC), noise filter enable
register (NFEN0), port input mode registers (PIM0, PIM4, PIM14), port output mode
registers (POM0, POM4, POM14), port mode registers (PM0, PM1, PM4, PM14), and port
registers (P0, P1, P4, P14)).

• SFR used by serial array unit m cannot be written.
• Serial array unit m is in the reset status.
Supplies input clock.
• SFR used by serial array unit m can be read/written.
