The OCD Control register
Debugger. This register is used to enter or exit DEBUG mode and to enable the
instruction. It can also reset the Z8 Encore! XP F1680 Series device.
Read Baud Reload Register (1BH)—The Read Baud Reload Register command
returns the current value in the Baud Reload register.
Write Test Mode Register (F0H)—The Write Test Mode Register command writes
the data that follows to the Test Mode register.
Read Test Mode Register (F1H)—The Read Test Mode Register command returns
the current value in the Test Mode register.
Write Option Bit Registers (F2H)—The Write Option Bit Registers command is
used to write to the Option Bit configuration registers. The Option Bit configuration
registers store the device configuration and are loaded from Flash every time the Z8
Encore! XP F1680 Series is reset. The registers may be temporarily written using this
OCD command to test peripherals without having to program the Flash Information
Area and resetting the Z8 Encore! XP F1680 Series. The ZilogUserSel bit selects
between Zilog Option Bits (1) and user Option Bits (0).
Read Option Bit Registers (F3H)—The Read Option Bit Registers command is used
to read the Option Bit registers that store the device configuration that is read out of
flash when the Z8 Encore! XP F1680 Series is reset. The ZilogUserSel bit selects
between reading Zilog Option Bits (1) or user Option Bits (0).
