11 / 28 page  2001 Jun 19 11 Philips Semiconductors Preliminary specification Bluetooth Adapter IC PCF26100 6.3.2 RESET The PCF26100 is reset with a Power-on reset using the VIO_POWER signal. This will reset all registers and put the device into a known state. The POR_EXT reset signal will also reset the device and put it in the same state as the Power-on reset. However, POR_EXT is intended to be used for a reset from a host. Following the Power-on reset or a reset by POR_EXT, the system oscillator is started and the SYS_CLK output is activated (enabled). The SYS_CLK output can be controlled by the SYS_CLK_REQ signal but only if the ‘rdy’ bit in the Control Register has been set to logic 1. The function of SYS_CLK_REQ has 2 phases: 1. After reset, SYS_CLK_REQ is not taken into account for the generation of SYS_CLK. After reset the 13 MHz system clock is enabled on SYS_CLK. 2. Once the ‘rdy’ bit is set to logic 1, the 13 MHz clock on the SYS_CLK is controlled with SYS_CLK_REQ. The SYS_CLK_REQ signal will not control or disable the oscillator. The LPO_CLK output is only controlled by the POR_EXT signal which also controls the POR output. The POR is activated 4 SYS_CLK cycles after POR_EXT. handbook, full pagewidth MGT755 phase 1 Rdy = 0 phase 2 Rdy = 1 POR VIO_POWER LPO_CLK SYS_CLK_REQ SYS_CLK OSC POR_EXT Fig.4 Reset timing. |
