5.3.1 Peripheral enable register 0 (PER0)
The PER0 register is a register that sets the clock to be enabled or disenabled to be supplied to
each peripheral hardware. Reduce power consumption and noise by stopping clocking unused
hardware.
To use universal timer unit 0, bit0 (TM40EN) must be set to 1. The PER0 register is set via an 8-bit
memory operation command. After the reset signal is generated, the value of the PER0 register changes to
00H.

Note 1 To set the general-purpose timer unit, the following registers must first be set in the TM4mEN bit 1. When the
TM4mEN bit is 0, the value of the control register of the timer array unit is the initial value, ignoring the write
operation (timer input and output selection register 0 (TIOS0), noise filter enable register 1 (NFEN1), noise filter
enable register 2 (NFEN2), port mode control register PMCx, Port mode register PMx and port multiplexing function
configuration register PxxCFG).
