11. MASK OPTION
The
PD754244 has the following mask options:
Mask option of P70/KR4 to P73/KR7
On-chip pull-up resistor connection can be specified for these pins.
(1) Do not connect an on-chip pull-up resistor
(2) Connect the 100-k
(typ.) pull-up resistor bit-wise
Mask option of RESET pin
On-chip pull-up resistor connection can be specified for this pin.
(1) Do not connect an on-chip pull-up resistor
(2) Connect the 100-k
(typ.) pull-up resistor
Standby function mask option (
PD754244 only) Note
The wait time when the RESET signal is input can be selected.
(1) 217/fX (21.8 ms: @ fX = 6.0-MHz operation, 31.3 ms: @ fX = 4.19-MHz operation)
(2) 215/fX (5.46 ms: @ fX = 6.0-MHz operation, 7.81 ms: @ fX = 4.19-MHz operation)
Note This mask option is not provided for the
PD754144, and its wait time is fixed to
56/fCC (56
s: @ fCC = 1.0-MHz operation).
