POWER-UP/-DOWN SEQUENCE AND RESET
The PCM1772 device has two kinds of power-up/-down methods: the PD terminal through hardware control and PWRD
(register 4, B0) through software control. The PCM1773 device has only the PD terminal through hardware control for the
power-up/-down sequence. The power-up or power-down sequence operates the same as the power-on or power-off
sequence. When powering up or down using the PD terminal, all digital circuits are reset. When powering up or down using
PWRD, all digital circuits are reset except for maintaining the logic states of the registers. Figure 21 shows the
power-up/power-down sequence.
