4. Data memory
The general purpose data memory is organized as 176* 4 bits. Because of its static feature, the RAM can retain data after the
CPU enters STOP or HALT mode.
5. Oscillator circuit
5.1. Circuit Configuration
SH67P53 has two on-chip oscillation circuits OSC and OSCX.
OSC is a low frequency crystal (Typ. 32.768KHz) or RC (Typ.262KHz) determined by the OTP option. This is designed for low
frequency operation. OSCX also has two types: ceramic (Typ.455KHz) or RC (2M to 8MHz) to be determined by the software
option. It is designed for high frequency operation.
It is possible to select the high speed CPU processing by a high frequency clock and select low power operation by low
operation clock. At the start of Power on reset, Pin reset and low power reset initialization, the OSC starts oscillation and OSCX
is turned off. But at the start of WDT reset initialization, the OSC starts oscillation and OSCX remains the original state.
Immediatly after reset initialization, the OSC clock is automatically selected as the system clock input source.
