No Connect
These pins MUST be left unconnected.
4M Input Clock Mode 0 to 1 (5 V-Tolerant Input with internal
pull-down) These two pins should be tied together and are
typically used to select CKi = 4.096 MHz operation. See Table 7,
“ZL50020 Operating Modes” on page 32 for a detailed explanation.
See Table 13, “Control Register (CR) Bits” on page 39 for CKi and
FPi selection using the CKIN1 - 0 bits.
ST-BUS/GCI-Bus Frame Pulse Outputs 0 to 3 (5 V-Tolerant
Three-state Outputs)
FPo0: 8 kHz frame pulse corresponding to the 4.096 MHz output
clock of CKo0.
FPo1: 8 kHz frame pulse corresponding to the 8.192 MHz output
clock of CKo1.
FPo2: 8 kHz frame pulse corresponding to 16.384 MHz output
clock of CKo2.
FPo3: Programmable 8 kHz frame pulse corresponding to
4.096 MHz, 8.192 MHz, 16.384 MHz, or 32.768 MHz output clock
of CKo3.
Generated Offset Frame Pulse Outputs 0 to 2 (5 V-Tolerant
Three-state Outputs)
Individually programmable 8 kHz frame pulses, offset from the
output frame boundary by a programmable number of channels.
ST-BUS/GCI-Bus Clock Outputs 0 to 3 (5 V-Tolerant
Three-state Outputs)
CKo0: 4.096 MHz output clock.
CKo1: 8.192 MHz output clock.
CKo2: 16.384 MHz output clock.
CKo3: 4.096 MHz, 8.192 MHz or 16.384 MHz programmable
output clock. 32.768 MHz if in multiplied clock mode.
