3. Operation
This section explains the functions and basic operations of the
TMP90C051F by block.
3.1 CPU
The TMP90C051F includes a high performance 8 bit CPU. For
the function of the CPU, see the book TLCS 90 Series CPU
Core Architecture. This chapter explains exclusively the func-
tions of the CPU of TMP90C051F which are not described in
the the book.
3.1.1 Reset
Figure 3.1 (1) shows the basic timing for the reset operation.
To reset the TMP90C051F, it is necessary to maintain the
RESET input at “0” for at least 10 system clocks (10 states: 2
microseconds with a 10MHz system clock) with the power
supply voltage within the operating range and stable internal
oscillator operation.
When a reset is received, the address data bus (AD0 - AD7),
address bus (A8 - A15), P36, P37, port 4 port 5 and port 6 are
all set to input port status (high impedance). Dedicated output
port 2 (A16 - A22) ALE is set to “0”; P30 - P35, RD, WR and
CLK are set to “1”. The other dedicated output ports are all set
to “0” and the dedicated input ports retain their current status.
The CPU registers and external memory are not changed;
however, the program counter PC, interrupt enable/disable
flag IFF, bank registers BX and BY are cleared to “0”. The A regis-
ter is indeterminate.
When the reset is released, the instruction starts from
address 0000H.
