CC2510Fx: Applies when 26 MHz crystal oscillator is used.
Maximum system clock is 13 MHz when high speed RC
oscillator is used.
CC2511Fx: Applies when 48 MHz crystal oscillator is used.
Maximum system clock is 13 MHz when high speed RC
oscillator is used.
See item 1, Figure 1. This is the shortest pulse that is
guaranteed to be recognized as a reset pin request.
See item 2, Figure 1.This is the shortest pulse that is
guaranteed to be recognized as an interrupt request. In
PM2/3 the internal synchronizers are bypassed so this
requirement does not apply in PM2/3.
