(1) All removable ports among variable ones support Battery Charging.
(2) The port with the biggest number among variable ones supports Battery Charging.
(3) The port with the smallest number among variable ones supports Battery Charging.
Note 1: To enable Battery charging function under S3/S4/S5,
μ
PD720210 must remain powered under
S3/S4/S5. When the power is supplied only in S0 and S3, the charging function is only available in
those power states.
Note 2: When “wake on connect function” and “wake on disconnect function” are enabled, BC modes are not
available, because these functions need to detect device attach or detach.
[With the external SPI ROM]
μ
PD720210 supports the Battery charging modes shown in Table 6-2.
In this case, modes can be set by the
μ
PD720210 ROM Writing Tool for Windows (W210ROMTOOL.exe).
From Port 1 to Port 4 can be set individually regardless the pin strapping.
