TMP90C400/401
3. Operation
This chapter describes the functions and the basic operations
of the TMP90C400/401 in every block.
The following is a description of TMP90C400 which can
also be applied to TMP90C401, if not specifically defined
otherwise.
3.1 CPU
The TMP90C400 includes a high performance 8-bit CPU. For
the function of the CPU, see the book TLCS Series CPU
Core Architecture concerning CPU operation. This chapter
explains exclusively the functions of the CPU of TMP90C400
which are not described in th that book.
3.1.1 Reset
The basic timing of the reset operation is indicated in Figure
3.1 (1). In order to reset the TMP90C400, the RESET input
must be maintained at the “0” level for at least ten system
clock cycles (10 stated: 2
μ
sec at 10MHz) within an operating
voltage band and with a stable oscillation. When a reset
request is accepted, all I/O ports function as input ports (high
impedance state). The P26 (RD), P27 (WR) and CLK pins that
always function as output pins turn to the “1” level. The dedicated
input ports remain unchanged. The registers of the CPU also
remain unchanged. Note, however, that the program counter PC,
the interrupt enable flag IFF are cleared to “0”. Register A shows an
undefined status.
When the reset is cleared, the CPU starts executing
instructions from the address 0000H.
