3.1
CPU
TMP93CF76/CF77/CW76/CU76/CT76 devices have a built-in high-performance 16-bit CPU
(900/L CPU). (For CPU operation, see TLCS-900/L CPU in the previous section).
This section describes CPU functions unique to the TMP93CF76/CF77/CW76/CU76/CT76
that are not described in the previous section.
3.1.1
Reset
To reset the TMP93CF76/CF77/CW76/CU76/CT76, the RESET input must be kept at 0
for at least 10 system clocks. (1.25 μs at 16 MHz) within the operating voltage range and
with a stable oscillation.
When reset is accepted, the CPU sets as follows:
Program Counter (PC) according to Reset Vector that is stored FFFF00H to
FFFF02H.
←
stored data in location FFFF00H
PC (15:8)
←
stored data in location FFFF01H
PC (23:16)
←
stored data in location FFFF02H
Stack pointer (XSP) for system mode to 100H.
IFF2 to 0 bits of status register to 111. (Sets mask register to interrupt level 7.)
MAX bit of status register to 1. (Sets to maximum mode)
Bits RFP2 to 0 of status register to 000. (Sets register banks to 0.)
PC (7:0)
When reset is released, instruction execution starts from PC (reset vector). CPU
internal registers other than the above are not changed.
When reset is accepted, processing for built-in I/Os, ports, and other pins is as follows
Initializes built-in I/O registers as per specifications.
Sets port pins (including pins also used as built-in I/Os) to general-purpose
input/output port mode.
Note:
By resetting, register in the CPU except program counter (PC), status register
(SR) and stack pointer (XSP) and the data in internal RAM are not changed.
