3. Operation
This section explains the functions and basic operations of the
TMP90CM38 in blocks.
3.1 CPU
The TMP90CM38F has a built-in, high performance 8 bit
CPU.
For the operation of the CPU, see the book TLCS 90
Series CPU Core Architecture.
This section explains the CPU functions unique to the
TMP90CM38 that are not explained in “that book.
3.1.1 Reset
Figure 3.1 (1) shows the basic timing of reset.
To reset TMP90CM38, it is required that the power supply
voltage is within operating range, the internal oscillator is sta-
bly functioning, and RESET input be kept at “0” for at least 10
system clocks (10 states: 2 microseconds with a 10MHz sys-
tem clock)
When a reset is accepted, among I/O common ports, port 0
(address data bus A0 - A7), port 1 (address bus A8 - A15) and
port 2 are set to input status (with high impedance). Output
ports P30 (RD), P31 (WR), CLK, and WDTOUT (P80) are set to
“1” and ALE (P83) is cleared to “0”.
CPU registers and external memory are not changed.
However, program counter PC and interrupt enable/disable
flag IFF are cleared to “0”. The A register becomes undefined.
When the reset is released, instruction execution starts
from address 0000H.
