PROM Mode
MSM64P155 has two different modes; PROM mode used to write to PROM and read
from PROM and microcontroller operation mode used to execute programs written to
PROM. When MSM64P155 is set in the PROM mode, it simply operates as PROM. These
operations are explained under PROM mode.
4.3.1
Setting the PROM Mode
Setting of the PROM mode is done with RESET, TST1, and TST2, listed in Table 4-2.
When the PROM mode is set, LCD pins become PROM-related pins.
