vi, vii When using the on-chip emulator (E7, E8) for H8/36087

program development and debugging, the following

restrictions must be noted.

1. The NMI pin is reserved for the E7 or E8, and cannot be

used.

3. Area H'D000 to H'DFFF is used by the E7 or E8, and is

not available to the user.

5. When the E7 or E8 is used, address breaks can be set as

either available to the user or for use by the E7 or E8. If

address breaks are set as being used by the E7 or E8, the

address break control registers must not be accessed.

6. When the E7 or E8 is used, NMI is an input/output pin

(open-drain in output mode).

7. Use channel 1 of the SCI3 (P21/RXD, P22/TXD) in on-

board programming mode by boot mode.

Bit Bit Name Description

3 NESEL Noise Elimination Sampling Frequency Select

The subclock pulse generator generates the

watch clock signal (φW) and the system clock

pulse generator generates the oscillator clock

(φOSC). This bit selects the sampling frequency of

the oscillator clock when the watch clock signal

(φW) is sampled. When φOSC = 4 to 18 MHz, clear

NESEL to 0.

Section 8 RAM

107 Note: * When the E7 or E8 is used, area H'F780 to H'FB7F

must not be accessed.
