7.3 Reset Action
Hardware Reset:
Hardware reset is performed by setting RSTN pin to low state for at least 1uS. The CPU data size will
set to 16-bit default, all the registers will set to default value. The receive and transmit data buffer will
be cleared, all the internal logic will be reset to initial state.
Software Reset:
Software reset is executed by write the RST bit of the control register to 1, all the internal logic will be
reset to initial state and receive and transmit data buffer will be cleared, but the content of registers
are not affected. In W86L488AY, the port A and port B will reset at the same time if global software
reset in the global control register is set.
Data Buffer Reset:
Data buffer reset is used to reset the receive data buffer and transmit data buffer simutaneously, the
serial interface command will affected if the data receive or transmit command is progressing. Internal
logic state and the content of registers are not affected.
7.4 Clock Source
The clock source of W86L488 is the waveform of XTO pin, if crystal is connected, the frequency may
be from 3.58MHz to 25MHz, if the clock source is from external clock, XTI may be used as clock input
and the maximum frequency is 25MHz. In W86L488AY, the clock driver will disabled when port A and
port B are power down or global power down in the global control register is set.
