OTP Option Bit Description
One-Time Programmable EPROM option bits for the device are described in this section. The
Z86E02 SL1925 must be power-cycled to fully implement the selected option after
programming.
Low-EMI Emission. The Low EMI option bit, when programmed, enables the Z8 to operate in a
low-EMI emission (low-noise) mode. Use of this feature results in:
•
•
•
•
RC Oscillator. The RC Oscillator option bit, when programmed, enables the inter-
nal RC oscillator to connect to the XTAL2 and XTAL1 pins while disabling the
internal crystal oscillator to XTAL2 and XTAL1.
(Volts)
All pre-driver slew rates are typically reduced to 10 ns
Internal SCLK /TCLK operation limited to a maximum of 4 MHz–250 ns cycle time
Output drivers typically exhibit resistances of 200 ohms
Oscillator divide-by-two circuitry eliminated
